All of Obsidian's artists are pretty awesome. If you've seen any of the concept art behind our games, then you'd know that. Anyway, I was thumbing through the personal site of Justin Cherry, our art director, when I found this sketch of Dante from DMC as a woman. Pretty interesting, as are the more final artwork that he has up there.

One of the funner things about working at a game company is seeing the concept art for things like characters and environments. I think some of Justin's work is also in some of the galleries for Obsidian games, like Mask of the Betrayer. I think this is another one of his, tho I could be wrong.
