Wow.
Beautiful dude. I know someone who would probably love to own something like that. I love dragons, but am not usually inclined towards the more Asian-influenced examples of them, but this piece pulled it off perfectly.
The detail is great as well.
I think this is more an issue of style than anything, but the only issue i have with this is the head is more humanoid shaped than one would think of an actual dragon with their long bodies, and more quadruped structured bodies.
