@harv: Arms and body are from the Flagellant box. I trimmed down one of the left hand weapons and added a small skull from the same box to it. The right I cut the top off, and added a beast skull from the Tomb Kings skeletons to the top. Head is from the plastic Greatswords.
@CommanderMorganBernhardt: I do a base colour, wash it then build up thin layers. Some of my paints are old, so I am not sure on the new names for them
Yellow: Iyanden Darksun, watered wash of Seraphim Sepia, a few layers of Flash Gitz Yellow and highlight with Bad Moon Yellow(Vallejo Game Colour) then a touch of Bleached Bone.
Red: Mechrite Red, watered wash of Nuln Oil, a few thin layers of Blood Red and a highlight of Blazing Orange.
@Gankom, Durloth: Thanks!
