Painting up Trollbloods (Pics + Recipe Request)

I'm going for a washed out purple skintone.  i start with a mix of Lich purple, black and grey and glaze up to grey + white.  Takes about 12 layers.  For the tartans and cloths, I go for random since I'm going for kind of a Junkyard/scavenger theme.

Pictures aren't the best examples for skin tone, but they're all I currently have.  Copied them from the WMW facebook page.  I'm hoping to be done with an extreme Mauler, Bushwackers and Horgle1+beast for the L&L painting competition this year.  Might be tough since I'm the slowest painter ever, and I now have a 2 month old who demands all my free time.
