Hello! I'm Diego Sanguino

Diego is an extremely professional and talented graphic designer; he worked hard to make my vision come to life and delivered perfectly! I will be working with him again in the future!

It was a pleasure to collaborate with Diego on what turned out to be a perfect cover for my novel. Two thumbs up.

Thank you for all your help and guidance throughout the design process. I look forward to the next project.

Diego was a pleasure to work with. He met the specifications and was competent with the design. And he created a book cover I am proud to show off. The colours and hues set the correct tone for the project. Thought went into every detail of the unique design.

Diego was fantastic. I’m a writer, not a cover designer. I don’t know what makes a great cover or what makes good advertising content. Diego helped with both of these and delivered a cover that fitted the tone I was looking for. I’ll definitely use his services again when it’s time for my next cover.

Diego was very kind and professional. A super talented, knowledgeable person and his process for creating the cover meant we had room to make adjustments pretty quickly and painlessly. I would gladly work with him again.

Working with Diego was truly the best choice I could have made! He delivered high-quality work that exceeded my expectations and made my vision a reality. If you’re looking for a cover artist, make Diego your first choice, you won’t regret it! I will 100% work with him again on future projects.

As a man of words, it's always been a bit of a challenge for me to communicate with those who think visually, but with Diego, there was no problem. He was sensitive to my neurotic protection of the identity of the main character of my novel and turned my ramblings and intimations into a book cover that I can truly say I am proud of, and I hope he is too. I thank him for his patience and understanding, and the clarity of his communications. It was indeed a pleasure to work with someone so professional.

Diego Sanguino designed the cover and interior of my book, and I couldn’t be more pleased with the result. He responded quickly and fully to my queries, of which there were many. He stayed with me throughout the process, from a concept Zoom call to uploading the final product. He understood the limited knowledge of a first-time author/publisher of fiction. I have no hesitation about recommending him and his work. Peter Harben

Diego was a pleasure to work with and I am happy with the result of our collaboration.

Diego responded to a great variety of requests. I picked him because of his understanding of the nature of the book, the expressive people he puts in his artwork, and his knowledge of Spanish and Aztec aspects of the story. I wanted a depiction of the three main characters of «Phase Shifts in the Old Vic House,» and Diego worked with me to add key features – including a specific type of gang tattoo, a tough-guy gold chain necklace, blood on a guy’s head, the Aztec Sunstone as a backdrop, and an Aztec mask used in a religious ritual. If my numerous additional details drove him crazy, Diego gave no sign of it. He was always professional. Clark A. Hiddleston, Author

Diego created book covers for Hephzibah and the Dragon, Profile in the Shadows, and His Brunette Alibi. He was responsive to my ideas. The project, eBook, paperback, and hardback jacket, was completed on time. The book covers are original and artistic and uploaded to the publishing platform without error.

As a first-time author venturing into the world of publishing, I had a lot of questions and uncertainties—but working with Diego made the entire process feel smooth and supported. His responsiveness was truly outstanding; every message I sent was met with a thoughtful, prompt reply that put me at ease. More than just delivering gorgeous artwork, he guided me with genuine care and expertise, offering insights that helped me make confident decisions. His creativity, patience, and professionalism made this debut experience unforgettable. I love the cover! Absolutely recommend him to any author—especially first-timers—looking for a true creative partner.

Diego is absolutely fantastic! He responded promptly to my request and arranged a meeting so we could discuss the matter further. I felt so relaxed during the process, with no pressure to rush through it. We took our time reviewing my project thoroughly. To make it even better, Diego completed everything faster than I anticipated. I’m looking forward to the chance to work with Diego again on my final book!

Diego did a fantastic job on my book cover for Paper Roses. Thank you very much!

Diego was attentive, engaging and, above all, listened throughout our collaboration, taking notes to make sure the changes were made properly. Whenever I reached out with questions or concerns, he replied promptly and was always willing to ensure that my concerns were met at all times. The collaboration was honest, and even when some of the design choices did not fit my vision, he was always willing to go back to the drawing board and bring me something fresh and exciting visually. The final design needed some big changes, and he met my expectations. I highly recommend Diego to anyone in need of a cover design.

A thoroughly professional individual with excellent quality work, who consistently thinks outside the box. Great communication and swift responses. Highly recommended!

Diego was fantastic to work with and the results for my book cover were better than I could have imagined. Thank you, Diego, for all your creativity and for always communicating with me until the end.

Having someone create artwork for my story was a new experience for me, and I wasn’t sure what to expect. Diego Sanguino was exceptionally kind throughout the process. I loved some of the details he created right away, and he was quick to respond to my many questions and suggestions. The finished illustration is one I’m extremely proud to share.

Diego was terrific! This was my first time working with someone on Reedsy, and I couldn’t be happier. Diego went above and beyond – his responsiveness and attitude were great. The finished product is equally awesome! Everyone on my team or in my close circle love the cover, and how much it captures the essence of my book. I will absolutely recommend Diego to anyone, and plan to use his services again in the future.

Working with Diego was brilliant, from the first day to the last. He listened to everything I had to say, took all my criticism on board and delivered a result that surpassed my expectations. He didn't shy away from adding his own ideas, most of which were incorporated because they were just that good. Seeing what started as a rough idea in my head come to life in such a masterful way is a wonderful experience. Every deadline was met and everything I wanted was included. As a debut author, I'm amazed that I was so fortunate to work with Diego. It goes without saying that I'd recommend working with him any day!

Diego was a pleasure to work with. His professionalism, creativity, and clear communication made the process smooth from start to finish. He quickly understood the vision and delivered outstanding design work that exceeded our expectations. We highly recommend Diego and would gladly collaborate with him again.

Highly professional, supportive, and adaptable. Demonstrates great flexibility and a strong willingness to act on feedback, making collaboration seamless and effective.

Diego is the first and best digital artist I have spoken with. I have had several projects where he has helped bring those visions to life. From book covers, book trailers, marketing materials, logos, and more, he has assisted with any and every request. Diego’s work is extraordinary. I’m so excited for the next project. Diego, keep being the amazing digital artist you were meant to be.

Diego took the time to understand my book, its purpose and message. So the cover he designed felt spot on. I appreciated the way he proposed possibilities and then made adjustments. And, of course, he is a talented and creative artist, as demonstrated by his portfolio.

Diego is a talented artist who was great at expanding on my initial ideas with his own creative flair. As the art was being worked on, he was responsive and collaborative to ensure the end product was one I would be satisfied with. I thought some times my responses were too wordy or would need clarification, but he said that for the most part he understood what I was asking. It was exciting seeing the artwork come to life. Diego was generous with both his time and insight. I will certainly work with him again.

I really enjoyed working with Diego. He was responsive and communicative throughout the process and his work was excellent. I will use him again for future work and I highly recommend him for anyone considering a cover design. Five stars all the way.

Diego is definitely someone you should collaborate with for your book design! His initial draft options for my new ebook cover were intriguing to view, and almost with a magical pull, I loved one of the three options he shared with me. We went with the one I loved, and he included some other features he provides, such as mock-ups and social media posts. The best part was that he used the ebook cover to help update my paperback! Now both books are illustratively symmetrical with one another, and what’s great about Diego is that he can provide in-book illustrations if you wish to redesign the interior of your paperback or ebook. Bonus: he can also create an audiobook cover for your book if you ask him for it! I shouted him out on my LinkedIn.

Diego was an exceptional collaborator in bringing my novel cover to life. He combined professionalism with a personal touch, effortlessly translating my ideas into a striking visual. His artistic skill is outstanding, and I couldn’t be happier with the final result. I’d gladly work with him again—I’m already planning a sequel and other projects, and Diego will be top of mind thanks to this fantastic experience.

This was my second time working with Diego. I’d previously found a book cover designer here on Reedsy, and when she stopped working, I had to find a new one. Diego is incredible to work with, and his passion for creating distinct and original covers that accurately display the book’s genre is brilliant to see. I’ll continue to choose Diego for every subsequent project I have!

Working with Diego was an outstanding experience from start to finish. He delivered a book cover that exceeded my expectations—not only visually stunning, but perfectly aligned with the tone and themes of my novel. His professionalism, responsiveness, and attention to detail made the entire process smooth and enjoyable. Diego took the time to understand my vision, offered insightful design direction, and communicated clearly at every stage. He met every deadline and delivered high-quality files ready for print and digital distribution. The final product was not just a cover—it was a statement piece that brought the book to life. I would highly recommend Diego to any author seeking a designer who blends talent with professionalism and truly cares about the end result. Gracias, Diego, for elevating The Slightest Mistake with your incredible work!
