You know, for the longest time, I really didn't want to paint these guys. I was unsure of the colors I wanted to use on them. I was afraid that I would paint their overalls in the same shade as my Space Wolf power armor, and that would look silly. I was a little apprehensive about painting the skin on these guys as I wanted them to look wasted and pale, almost dead (as servitors appear in my mind).
For the skin I chickened out and painted them "swarthy" as I painted my Space Wolves. The reason I'm going to use is that they are from Fenris, and perhaps failed aspirants so they are going to have the same completion as the Astartes.

One of the things I like is painting the little details. I love these little lights I have painted on each of the backpacks.

I really like the cyborg arm one a couple of these guys. They did a great job of the transition and metal grafts on the arms.
