I think it's a lizard. I think it's a he. I'm in the middle of drawing today's comic and figured I'd share this monstrosity with you. He's eating chicken.
I'm not sure how to make a lizard look female, since they don't have breasts. I think it would all be in the eyes and mouth. There might also be some species-specific traits. Would it be wrong to have a topless female lizard if there aren't any titties?
