Totenkopf

Hehe, yeah, I do seem to be flying through avatars at the moment.

Hopefully this one will stay a little longer than either of the christmas themed ones (with have barely lasted a week each). I think it looking Sithy/Sinister is why I like it. And you're right, it does look very similar to the cover art for Assassin's Creed II. Looks like LA have been taking lessons from Ubisoft.
