The above image is behind the scene process of what I went through roughing the pages. I would make about three to five roughs and flush them out.
This is one of the roughs I liked best and detailed before printing it in non repro blue ink. I would then pencil the roughs on paper.
In the image below, I worked on about ten roughs before selecting the one that looked good.
The following images are sketches I did before the script was written, and Stuart liked it very much and worked them into the script.
