The wonderful thing about skeletal undead (and mummies) is that they look so good even with just a drybrush of Dirty Bone!
I used... I don't remember which brown on the weapon shafts.
The demi-lich got Nightmare Black and Pine Green on the smoke. I lightened the green with Linen White. Debating whether to paint the bones up, or hide them...
I also used the green on the archer's cloaks, and the black on the robes of Death and the Lich-Lord (way in the back).
More to come!!
