Well, I wanted to get in on this one, and finally had a chance to sketch, and mock something up. Keeping it simplish in form, but that won't stop me from having a lot of fun with it.
My creature is sort of a mix between a hyena and an alien monkey/gorilla. Not sure where it came from just sorta went with where the skecth took me. Had spikes on his back first, but decided to make them tufts of fur instead.
Haven't sorted out what shape the ears will take yet, or what I'll do with the top of the head, if I'll carry the tufts of hair over to there as well or not. Probably figure that stuff out when I get there. I'd imagine the whole thing will change as I go along, but that can be half the fun.
Anyway I present the initial stages of my "Alien-hyena-monkey-gorilla" or something.
