Not much. Trying to draw my persona, DeNihil, in his Subjugator Ranger armor, but it's more complicated than I thought. I thought I was good at armor and other non-organic things. :s
It's inspired by the armor worn by dirt bike riders, especially the helmet. The coloration pretty much matches the one of the SPARTAN-IV armor in my avatar. Green primary on armor, yellow stripes, black body glove, and white insignias.
