Very nice. He has a purely devoted look to him. Somewhere between a priest, and a soldier: Henceforth, a paladin. He seems comfortable with fighting and bloodshed, but not unless there's a more diplomatic means by settling something instead.
Excellent work! I'd like to see the chest plate (especially the skull part) with a little more rendering, as the face seems to pull far more attention than the rest of the drawing, but excellent work! The details are incredible
