I wasn't great about taking a bunch of pics along the way so far, but here are what I have: Both minis got a soap bath with warm water, Dawn dish soap, and a good scrub with a toothbrush. Once dry, I primed the pony with Reaper's Brush on Primer - which I had to scrub off with soap and reprime three or four times before it would not bead up. Then they both got a coat of Brown Liner:
As you can see, I picked out a 30mm base for the pony. I haven't dug through my bases yet for the bull. I then hit them with a blotchy coat of Ancient Bronze, then Lava Orange, and then Bloodstain Red.
