I decided to paint a thin band of warpaint on this one. I had painted and highlighted the face and then added the warpaint. I used 50/50 mix of Chaos black/Scorched brown, I thought pure black may have been to harsh. The paint was thinned so I applied a couple of thin coats to build it up. Again I did not want to destroy the detail, so the original skin colour underneath can in places just be made out. The warpaint looks more brown in the photos but on the actual model it does appear to be more black.
