Cute idea, but right now, what you are describing sounds more like a poem to me. To make it a picture book, my suggestion would be to think, not in terms of stanzas, but in terms of action. Is there enough variation and building of action to warrant 14 page turns, or will each spread be similar with just an added layer to the sandwich. Is there a way you can take this cute concept and go even more crazy with it - in a way that would intensify the action and variation of the visual?
