The detail stands out, the dragon has a good solid shape, plus I like the shading.
But my one weak spot is the legs, perhaps you could have had the front legs move back a teeny fraction and had the dragon's front elevated a little bit, it kind of seems like he's struggling to keep balance.
I think what might be throwing it off is the back rear leg. Or just the rear legs in general. I'd have to disagree with the front legs or I'm just not seeing it.
