He looks good overall. I agree that the armor looks nice, so does the coat. The horns on the helmet look fine as well, and the base seems more than adequate.
All this makes it even more disappointing that the face has been painted so flat. IMO that is what makes or breakes a figure. Some more contrast there, and maybe some life/color in the eyes and it would score a couple of points higher.
BTW these models are great. Big fun.
