I couldn't be happier with my cover and the whole experience with Sandro!
The cover looks so high-quality and professional - the facial expressions so perfectly convey the characters, and he beautifully captured the underwater, spooky, magical atmosphere I dreamed of! He's also clearly an expert on how to construct a design (e.g. the right positioning of elements to draw the viewer's eye to the right place).
Sandro is also wonderful to work with, super responsive, and fast - and when I came to him with challenges I couldn't imagine how to workaround, he amazed me time and time again with the solutions he found! (For example, when I said: "Without showing X in this scene -- where it doesn't belong -- I want to give the impression that there will be X in other scenes in the book...")
