First time I do NMM on such large areas, and my 3rd atempt overall. I'm most satisfied with the gold, and a bit less satisfied with the blade.
The wrinkles in his head is to dark, I've toned them down a bit. Main focus is the NMM, as this is the last part in my step by step.
Colours are GW Codex gray, with some Enchanted blue added, then more and more white for highlights. For gold I used Snakebite leather, with a small amount of sunburst yellow added in the later stages. Again, skull white was used more and more with each step.
