As promised ner vod, I have a detailed version of the pattern (which is very simple) on the right. It runs down the center of the helmet, and along the weakhand (left) side from shoulder to toe, down each plate in a contrasting color with the plate color. I was also thinking, if you're using a metallic base paint to weather with, you may think about having the details in the base color, to make it look like deliberately exposed metal... I thought that'd be kinda cool. I also thought that if you don't like the vertical pattern, you could wrap it around the body, going from the top left and down across the chest, around the back and down the left or right leg, or both really... but have it descending and wraping around the body, even twisting it so that the razors and barbs are on different sides at times.
