I really like these models, and they are very in character for any Ork army.

I started off with a black undercoat and then did all the metallic bitz with a drybrush of tin bitz and chainmail.

I then did the Ork skin with a dark green, highlight with Goblin Green before doing final highlights with a mixture of Goblin Green and Bleached Bone.

The orks’ teeth are first done in Bleached Bone before final highlights of Skull White.
Uniforms (and I say that in the broadest possible sense with orks) are usually Codex Grey with highlights in a lighter grey.

Bases to fit in with the snow based theme and Cityfight games are done in Codex Grey before drybrushing with Skull White.
