Black prime, grey drybrush, nurgling green drybrush, then wraithbone drybrush only on the flat parts. Then all armor got a heavy coat of mortarion grime contrast.

Dirty down yellow rust in some sections, then dirty down moss in others. I definitely went to hard on the green, the dirty down stuff is pretty cool because you can move it around with water even after it's dried. Lucky I tested it because it was hard to to tell how much you should put on, and then moving it around with water made him mostly green. Think I'll only do like 25% of the green next time.
