I primered the figures with Krylon Colormaster Ultra Flat Red Oxide. Then I coated the figures with a wash of a 50/50 mix of Agrax Earthshade and Carroburg Crimson. After that, I applied successively lighter layers of Mephiston Red and Evil Sunz Scarlet. Finally I applied a light drybrush of Ratskin Flesh.
Yellow trim and skin-tone base colors down. Still lots of shading and highlighting left before finishing the base with grit, paint and static grass.
