Did these the other day, they were inspired by some warmups that I did for this past Tuesday's comic (10-28-08). I quite like drawing Skull from PvP. I'll post the warmups soon.

I recently did a bunch of sketches of other webcomics characters. The comics they're from are:
(from the top) Capes N Babes, Marooned, Ominous Knife, Calamities of Nature, and Fancy Secrets.
