His fur and skin look really damn good. His horns, claws and teeth look like they could use another visible layer between the dark brown base and the light colored highlight but otherwise, great job man. I just thought of something cool too, what if you were to paint the eyes like they were glowing? Like say, a Scab Red base in the sockets, then Red Gore in the centers leaving a bit of the previous color showing, after that a smaller amount of Blood Red in the middle of the Red Gore and then a tiny Blazing Orange dot in the very center of the Blood Red eye. Give him baleful eyes. I bet it'd be cool looking.
