I like the overall, misty appearance of this picture, and honestly, I really love the amount of work and detail you put into your background. That piano looks incredible! Something about his head is bothering me, but I'm having trouble placing what it is. At first glance, I thought it was too large, but in quick measurement I don't think that's the case. I think his face is kind of long, almost stretched looking, but overall I can't find a lot to critique here. It turned out very nice! The bright blue keys do kinda stand out in an awkward way, though, as if they don't match the rest of the picture somehow.

This is a surprisingly peaceful piece in your gallery which I rather like - the little birds just about make the scene alongside the sleeping dragon, he must be pretty good at playing if he can soothe such a mighty beast too : )
