This is just a quick update to prove I'm still making progress.
I've had some Dragonforge bases that I've been sitting on for a while so I decided to get them set up for the new Iron Hands. After blue-tacking them to an old box and some airbrushing followed by a little hand painting they're ready to go. I used GW Steel Legion Drab for the base color with a careful wash if GW Agrax Earthshade in the recesses. I finished with a light drybrush of GW Underhive Ash followed by GW Terminatus Stone. I'm pretty pleased with the results and, when I receive my next order of bases from Dragnforge the paint scheme will be easy to duplicate.
Just a note on the citadel dry paints, I scoffed at them after their initial release but now that I've used them a few times I think they're a solid addition to the Citadel range. My only gripe is that some of the lighter colors would be useful as layer paints as well, though it's just as easy to find some equivalents from other paint ranges.
