I have taken advantage of advice painting NMM, written in painting guide by Yellow_one
http://www.chen-la.com/articles/pawn.html - this guid is amazing
You're right, the guide is amazing, and I can't even read it! I couldn't get Babel to translate it either, which made me very sad. The pictures alone are worth bookmarking the reference, though! You've done a great job with both the NMM and the cloth, and the realistic "dirt" on him. Wonderful job.
