I think his comment meant to point out the paper cut out quality of the illustration. Also that only some pieces look outlined, some objects are only partially outlined. and light doesn't fall off as you move away from the light source.

If this is a style you like and want to develop then it's ok, but if it's not something you like you may want to make the illustration look more painterly and less flat of course with more consistency as smceccarelli said.
