Nice warlock, I am painting my Avatar now for my Ulthwe' army! The only things I see that could help yer score is the fur on his back could use another color...he's already all black, lol and the base, but I'm sure you haven't done it yet is all. try to get him planted firmly on the ground when ya do .
not too bad! the highlighting on the bone is really good and the paint job is clean. try some subtle highlights and turn the eyes into gems and it really looks awesome!
