Tried something a bit different with these guys. Started with a black printer, with a Grey Seer zenithal over top, and then a pure white dry brush.
Over that, my new favorite contrast paint, Imperial Fist, to get the majority of the model done, with a black wash to dirty it up, and make edges and creases stand out more.
Definitely could spend another 20 hours refining all the details and making the armor look better, but for what I wanted out of a fairly quick paint job, I'm happy with these results.
Nice job! They look great.
