I know the colours on him stink, but it's tied into a christmas theme for a warband. He was painted for the warband painting contest where the prize was a tom kings army.
Was this the Chaos Warband Conversion contest? I was going to enter, but then felt suddenly inadequate. If you entered in my area, I'm glad I backed down. Where are you from anyhow?
I'd love to see the rest of the warband. This model is very cool.
