Drawn from memory after looking through pictures of different deer, antelope, and bison skulls. Antelope make me think of grasslands. I spent a few good summers working on prairie restoration projects around Kane county, IL. There really is nothing like the grasslands, the soundtrack of millions of birds and insects. It really buries you especially when the grass grows 8 feet tall. No Antelopes on my Illinois prairies, but this drawing takes me there anyway.
