For the brown, I think I used Vallejo Model Air Tank Brown, or Vallejo Mud Brown, or a combination of both. I know I used Reaper Burgundy Wine for the shadow.
For the skin, I used Vallejo Model Air Skin Tone, but it really paled to a yellow tone, over top the white primer. I didn't bother with a second coat, since I knew I would be applying paint with a brush at some point.
The spray pattern for my airbrush is pretty bad. I learned later that I had already bent my needle-tip. Grrrr..
Since I had nothing to lose, I removed the burr with a cosmetic emery board. That improved the pattern, but I'll probably buy a needle kit to replace it. I can also see if I can use the needle from the side-feeder, but I haven't gotten around to digging it out yet.
I don't like the direction that the color is going for the Union Workers. After much thought, I decide I'm going to go for a black leather. That will give a high-contrast backdrop for the shoulder-pads, swords, and heads. For color, I'll paint striped leggings. The crew will look like a rugby team!
I attempt to achieve a weathered leather look, by sponging liquid mask on the brown undercoat, before airbrushing on the black. I used Microscale Micro Mask. The experiment totally failed. After airbrushing on the black, I couldn't figure out a way to remove the mask. I couldn't even feel it. It was like it had totally dissolved. I tried using poster putty and masking tape to pull it off, to no avail.
Along the way, my Carnevale Kickstarter arrived from Vesper-On! And a gremlin from their new, forthcoming game, Home Invaders, invaded my stash! How cool is that!
I masked the swords with masking tape, and after airbrushing on Boltgun Metal, I airbrushed a filter made of my homebrew blue wash, a little burnt umber, and little Vallejo Thinner Medium. The underside of the shoulder-pads got it, too. I also experimented with airbrushing various tones on the underside of the skin.
Here, I added dark-lining, and I sponged on a highlight of Chainmail, followed by a brush wash of my homebrew blue wash.
