Dragon face

I rather like this fellow unfinished.  He has a very intense, intelligent look created by the shapes and shadows around the right side of his face, and the hand beside his jaw creates a sort of balance against the weight of the shadows on his right.  Those two elements are what first got my attention and set my impression of this dragon-ish character.  After that I noticed the shape of his lips/mouth--that's perfect for the "intelligent curiosity" expression--and those nostrils on the harmonious shape of his snout.  I think perhaps one more horn could be added to balance the one that hasn't got a mate at the moment, but beyond that I think he's artistically perfect as he is.  Adding more color or detail to him would only weaken him, I think.
