Not pictured - is the straight up primed only picture. So, here's Step 1 - which was "Dead Flesh" on the skin.
Step 2 - Purple on everything. I tried not to duplicate where they had purple, but there was two rotters who got purple tabards.
Step 3 - a combination of light brown and dead flesh for the Pestigor's fur.
Step 4 - Brown - leather-esque for other clothing bits.
Step 5 - White for the bone bits.
This far was done in roughly an hour or so of work over two days, with some touch-up for over paint where needed. I let them sit overnight, and then got on with the show.
