Heh, neat. The skin looks great, and the expression on his face makes him look like an irritable bastard, heh.
There\'s some thing about it that could be improved though... the legs most obviously. They look ok, except that the joints in the limbs (elbows, knees) aren\'t obvious enough. For a lizard kind of animal they should be pronounced. Also, the back and front feet don\'t look wide enough. Animals paws and claws tend to splay out a lot. Work on the details and I reckon this will come out top class.
