Several years back I did a whole bunch of card art for Fantasy Flight's Call of Cthulhu CCG. I did them digitally, but for a couple of pieces I went back and redid them in Oils. Of course, I think they looked a lot better that way!
So this is Ithaqua, a Great Old One from Lovecraft's Cthulhu Mythos (the character was actually a Derleth creation, an author who contributed greatly to the Lovecraft world). He's basically the Yeti from legend. This painting won an award for Best Horror in the Dragon*Con art show the year I displayed it there. The original version was both a card and the back cover for the Arkham Horror board game. (You can tell the difference on this one easily - the original has him holding a severed head.)
