I tried to capture the battered, worn look seen on the original inspiration.
Paints were GW Chaos black undercoat and a couple of drybrushes of Boltgun, Adeptus Battlegrey and then a very light Dheneb Stone. Details have a white basecoat and then blazing orange highlights. The "eyes" are scorpion green. There are a couple of panels, details here and there and some markings in Midnight blue. The whole thing then got a black wash and then a targetted Devlan Mud wash for grimy bits. The base was done in the usual way, Bestial Brown paint, PVA, Brown ballast, PVA, flock, cork boulders and Silfor Tufts.
Overall, I'm really happy. I think it captures the well used look of the original, and the revised torso blends in well.
