So often, I'm in  weaselgrease's streams. And he was drawing this maniacal looking creature. It had a long tail I interpreted it as a rat. I made the joke that the character needed a lab coat and wings. And sure enough, he added them to the drawing. (http://www.furaffinity.net/view/4605814 for the original line drawing)

Well, I asked for the original lineart to color it. This piece was the result. Not too bad. I'm sure if I could shade for my life it would be better but here you are!
