There's not too much difference between writing a picture book and writing a collection of a hundred poems or so, except that the bigger books take a lot longer to do.
Sentiment: NEGATIVE
I usually do at least a dozen drafts and progressively make more-conscious decisions. Because I've always believed stories are closer to poems than novels, I spend a lot of time on the story's larger rhythms, such as sentence and paragraph length, placement of flashbacks and dialogue.
