Genestealers are laid out and ready to go. Since I've never played Nids before, I had to ask on dakkadakka.com about the arm configs.
Here, you can see the test model (primed GW spray white, Bleached Bone base color, Dwarf Flesh and Chaos Black nails, Minwax Polyshade Tudor Gloss wash/seal), the 4 genestealers primed with gesso, and three that have just been assembled.
Of course, AFTER I primed all of them, I realized that I didn't attached the extended carapace. Ah, well. They are going to be red/black like the carnifex, unless it makes them look too much like shoulder pads. Welcome to the 80s.
