Haven´t participated in one of those conceptart.org weekly challenges for millennia, so in-between so much 3D modeling at work, I thought the Character of the Week challenge would be nice practice. I tested myself even further by only working on it during lunchtimes at work, that is, 5 sessions of 45 minutes, and left it as-is. Here's the result.
EDIT: Looks like it won. Woot :)
