Amazing work on the gorilla. He looks seriously pissed. The armor looks great, the fur is incredible. You have really done a lot with a very limited palette.
I think the skirt looks a little unfinished, though, compared to the rest. I guess I feel like it just doesn't measure up texturally to the work you've got everywhere else. I don't think you need a freehand design.
Bear in mind I could definitely not do as well. I'd still give you a 10 overall!
