Some years later I come here to steal the skull. I like that skull. I'll steal it and try some edits to see what happens. I have no idea if you still being active here as this post is from 2011 xD

Edit: I've done a bit of editing and posted it here: https://opengameart.org/content/some-skull-ive-stolen-from-a-random-guy-...

The skull is nice as a base to work with it, I should spend more time, but for now I just want something moving.
