I think it\'s a good start at working with NMM but with a few touches I think this one would have turned out even better. The first is the rivets, particularly on the leg and elbow, don\'t have a blend to darker tones around them, also on the fingers the joints need to be darker as well. Overall you do seem to have your hotspots working right, but the rest of the armor is generally too light. The result is a dull look to the armor, as if the surface is defusing light rather than catching it in spots and reflecting it. It\'s the dark areas that work to really make those hotspots \"bling\". I think the work you put into the chainmail sections turned out great.
A big point to remember with NMM is that it is in essence painting an illusion, so all those little details (such as shading around rivets), if missed, start to break down your illusion until you\'re left with greys instead of metal!
You\'ve shown a ton of potential with the technique here with your skilled blending, and with a few more models under your belt I have no doubt you\'ll perfect it.
