Was originally my final for the drawing class I never actually really showed up for. Blew up my 9"x12" drawing with a projector and cut the image out of a huge piece of black plastic. Placed construction paper underneath (wanted colored plastic but that stuff ain't cheap).
I actually picked up a book of Lovecraft's stories as I was working on it since I tend to draw squid creatures and wanted to find out what exactly Cthulu was. If I have read it before hand would have made him into Cthulu...take away four of the eyes and add some wings.
