This is a full-body pose that sort of grew out of this sketch: https://www.weasyl.com/submission/388217/evil-grin

Again done entirely with a mouse, but this time in Paint Tool SAI, or possibly GIMP. I really don't remember, it was a long time ago. I've been meaning to return to this one and fix it up and color it a bit, but let's face it, that won't happen any time soon.

The sketches for this contain a chair, but it was crap so I didn't line it. :P
