Awesome paint job. I particularly like the rich colors, the bold lines, and the expert shading. Definately eye-popping.
My only qualm with this one would be that the color gold seems o dominate everything. If that was your intention, you pulled it off marvelously. I personally would have broken it up a bit, namely the face mask with some iron or silver metallics. I can't stress enough how much this one jumps out at me though, well done!
