Way to go! I love this book for many reasons!
Most covers are cut and dry, meaning you can tell what's going to happen, eg. man about to kiss skeletal bride or kids just about to be seen/caught viewing a murder/secret happening. This cover you don't really know the story here, the boy doesn't look frightened so much as surprised to me. Why is he in a wheelchair? Is that creature there to hurt or help? Then there's the colors! That deep blue against that lime yellow/green! And of course the Kaluta art. Wow! Great all around, nice choice.
