Of note is my use of Iyanden Darksun for the yellow. My son bought me it, he'd originally wanted to get me a Space Marine Librarian but I bargained him down, as I don't need it and they are expensive. Also, I tried to get a standard acrylic craft paint to reduce my reliance on Bronzed Flesh to lighten the Vermillion for highlights. The best I could find was a 'pumpkin' colour, which is indeed a light orange. Still, mix in some brown and we were nearly there.
Lastly a close-up of the Stargate-esque iris hatch. Successive coats of Stonewall Grey but thinned to allow some of the Red Oxisde undercoat to show through. This gives a nice weathered effect. Some slight highlights on the chevrons with the yellow stippled on to give that mottled weathered effect, love it. Now what else can i build to go in the socket?
