Book Illustration Marker Comp

My marker comp of the book illustration went over pretty well. Some people wanted more in the background but I didn't want anything distracting. I might make the grey fade but I don't think there's a need for any more objects in the background. I'm not sure what medium I'm going to use for the final illustration of this one. I might try a combination of line and gouache, but either way I want to make it look less cartoony for the final.
