Pallid skin

I wanted Big Nasty to have somewhat of a skin condition. The base color was a purple and middletones was put down mixing purple and grey with a skin color. Lighter mixes of this blend was used for highlighting, and final highlights was purple and pallid wych flesh, and finally wych flesh on it's own. The whole lot was washed with a thinned down orgryn flesh wash. Now I just need to add some color diversity.
I also need to figure out something about the arms - way too monochrome.
