The series of illustrations don't seem to fit in with the given assignment. I would rethink and try to come up with something that goes a bit more humorous, or grave.

I think that there is a huge difference in how the two girls looking in through the pastry window are rendered. The top one that is a bit more sketchy feels more appropriate for a middle grade book, than the bottom one. The bottom one is more cute, like what you would see in a picture book category. So if you are going for middle grade, is it possible to draw all the folks to fit the sketch of the girl on the top?
