First squad of the army done! 

They're relatively easy to paint:

Armour:

Black undercoat

Khorne Red basecoat

Carroburg Crimson wash

Squig Orange edge highlight

Trim:

Leadbelcher Base

Nuln Oil wash

Ironbreaker edge highlight

Horns:

Rakarth Flesh base

Agrax Earthshade wash

Ushabti Bone highlight

Lenses:

Sybarite Green

I then added script using Ulthuan Grey.

The bases are:

Mechanicum Grey base

Agrax Earthshade wash

Screaming Skull drybrush

All nice and easy, if not the quickest way to paint them!
