This was something I've been wanting to get to work on for probably about a week now, and just today had the ambition to go digging around to find the scanner.
I'm sure this perspective has been illustrated before, but I started doodling this pose and fell in love with how it was turning out. :\
I'm actually really pleased with the way this looks. I'm in love with my first attempt at shading using a black opaque layer, so yay for me. I couldn't get the background to turn out quite the way I wanted it to initially (since GIMP's rendering of clouds is far different from PS7's), so I used some stock (linked below) for the gradient fill, and then plopped the clouds on there using a basic GIMP brush, and then motion blurred and cartoonified it.

Basic pencil and sketchpad for initial lines. GIMP for all "inking", coloring, shading, and compilation/addition of background.
