Willow painted this one, not me, and I think it kicks ass. I don't know all of the colors she used, but the head is probably Bad Moon Yellow and shading onto a duller yellow on its belly. The base color for the wings and the back of the nekt is Golden Yellow, with Scab Red becoming more prominent toward the middle of the body and the tail and coloring some of the wings. The horns, claws, teeth, and stinger are Chain Mail, and the base is mostly Codex Gray with a few bones picked out in Bone White.
I'm using this mini to represent Blacksting, a red wyvern half-dragon.
