Whooaa... so reminiscent of semi-detailed Asian influenced paintings--- the tones and shadings, and especially how blunt the brush seems. It looks amazing! You should make it full-scale with a whole battle scene to go along XD
I really like the sense of movement this has. It feels like Thorin is rushing forward towards something. The expression on his face is great too. They both do a good job of showing the desperation he has that a formal portrait can't.
