Originally,
I had planned to show the empty wheelchair from an aerial view with
butterflies streaming up towards the reader, but in working on the comps
I realized a straight on view was more effective for showing the stream
of butterflies.
Color Comp
This
comp went through about five versions---the most of any piece in
the book---and they kept getting simpler and simpler in
approach. I would show all five here, but they really aren't
very interesting.
