Technically I've heard that your not suppose to do page breaks for picture book manuscripts. How is a narrative poem (assuming that it's not a rhyming poem) treated if its simply arranged in scene breaks, but not necessarily page breaks?
I'm more naturally a poet (though not necessarily good poet), that is used to separating them in scene breaks that have a numeral heading.
As an aside: Found a recent picture book, though looking for recs. Also this is quite a change from what I'm used to doing, sense my work is often so dialogue-driven.
