A pretty crappy photo that doesn't do them justice, but I'm a crap photographer anyway. Some beastmen I painted up fairly quick. Mostly Contrast (the metallics and their turquoise belts are normal paints). I went for a brown/red/black scheme to match the rest of my chaos army (which is mostly Khornate in nature), and added some bits of color representing the other chaos gods (some purple and greens) as minor details, to represent that Beastmen are less likely to devote themselves to a single aspect of Chaos. Also, in the background you can see a bunch of Khorne knights that I'm nearly done with, but so much edge highlighting is driving me nuts, so I do that in small batches of one or two miniatures at a time, so stil a bit to go with them.
