Actually a variant on another image that was initially red, black, and grey, a friend asked me to make a blue version. Which I complied, and most people seem to like best out of the others I made.

All of which you can see on my Redbubble! - http://www.redbubble.com/people/haligren

The original version, titled "Blood Moon" on my Redbubble, was just a sort of art block-breaking doodle I whipped up when I got frustrated with trying to do commissions - hence the sloppiness. The werewolf looked nothing like the one I wanted to actually draw, and the face bore an odd resemblance to the way another well-known artist draws her werewolves, which I was able to change, of course.
