Overall this is pretty neat.
I think in general the textures could use some cleaning up, in the linked render the characters texture is rather blurry.
Also if that is the rendered scene and it is a final I'd suggest fixing the texture on the underside of the rock he's on as it is close to the camera so you should see lots of detail there. Right now it is a big blurry texture.
The model looks very cool.

Keep it up
