@Gary-Wilkinson I really love your character and prop design. It's consistent with your other work and that's something to be proud of. The colors here are harmonious and well planned. I'm new here and I stalked your work recently. It's obvious that you are at the top of the class.
I'm confused because there is no distinction between where the boy's environment and the imagination world collide. He is so crisp which makes me think he and his drawings are in front. But then I get the feeling that the crayon world is in front because of the high chroma and strong texture.
If I had any suggestions it would be to:
- define what's in front and what's behind
- maybe a drop shadow would help to separate the two spaces
- muting the colors of the crayon world
- bringing down those highlights in the crayon world to keep the contrast lower.
(I'm assuming you want the boy to be the subject since the book is about him. That's why I'm suggesting taking down the intensity of the of the crayon world.) I hope these suggestions help. I know personally I benefit from detailed feedback. Overall I really like it.
