I think it looks great! I sure can't draw cool stuff like that, not as well as that, anyway. The sword looks a bit like a giant bone, but maybe that's me or the black&white shading or something.
The only thing i can find which makes it look weird is that his left arm isn't in the sleeve of his coat. If he were to start fighting, his coat would come off and start flapping around, getting in his way!
