Justicar of Dorn Term Chappie by Battle Captain Corpus

This was part of Battle Captain Corpus' individual painting challenge: 1850 Army to TT quality in 31 days... Looks like a good time

This mini is what I imagine a RG Chappie looks like (inverted - mostly off-whites w/ black highlights)...

Very simple method to get his effect... The method is simply undercoated Skull White spray, then covered head to toe in Gryphonne Sepia wash by GW. I put on quite a lot, and its effects like you say are very similar to "dipping". You get a more gradual tone effect.
