Or maybe Step 2? I don't know. I think Step 1 was doing the bases.
I decided I wanted to do something a little different with the Plague Monks given that I'm going to have so many of them to paint. I primed the models white and then mixed up 50/25/25 Water/Abaddon Black/Death World Forest. The idea was sort of to make a sickly dark green wash that would go right over the white and do most of the inital shading for me. I think it turned out pretty well. I treated this just like a wash... slopped it on and then used the brush to make sure there weren't that many pools anywhere. The watery paints almost stains the white primer. It's a cool and easy effect.
I'll be painting the blades a rusty silver and the tail a nice rat tail pink. The skin will probably be Codex Grey with the brown wash on top of it. The rope belt will be tan. That should be enough color that I don't really have to highlight the robes any more than they're already highlighted. Time will tell.
Now the waiting game begins. These things take forever to dry.
