These dudes came with a some base colors already done. A black undercoat with a necrotic grey/green flesh drybrushed on top. I just picked out a few details and made sure to give one of them a slav ganger uniform - blue Adidas pants.
The last kind of the Sedition Wars sculpt is this beast, I call it The Witch. I figure it's a very nasty, stalking, silent killer. Again it has a really nice alien look. This one was base coated grey, had some metal and bone details picked out. The entire model is then covered in purple wash.
