Unnamable

Ok, the Unnamable by H.P Lovecraft.

Some of the first descriptions of the unnamable came across as a mix of goat/faun, and gorilla, so I ran with that:

Then I went with a bit more of a deformed look - melted skin and horns and stuff. Not so fictitious. There were heaps of references to a "blemish", so I really tried to make it as visual as I could - half his face melted off? Sounds like a blemish to me.

Werewolves were pretty popular back then, so I tried that out too:
