SO... the empty gut cavity was bugging me. A bit too empty and too clean. I've had my hands in many a body cavity (I grew up hunting), so it needed some love.
I'll let that harden overnight and prime it tomorrow. Then, on to painting. I'm enjoying the challenge... and have another one for August, but I have to admit I'm seriously jonesing to get at my Dark Imperium minis and to convert a bunch of poxwalkers. :)
