Thanks :) These are a lot of fun to paint. I primed the model black first, then painted the recesses of the skin with a mix of black and Vallejo Vermillion. Then I used a mix of Vermilion with just a touch of black for the next layer. Then a layer of pure Vermillion, than a layer of it mixed with Deep Yellow...about 5-6 layers in all. Obviously, each layer is smaller than the last so that the final layer is basically just an orange dot. In real life it looks quite dramatic, as it gives the skin a "glow". When the whole regiment is done I'll put them up on ebay. :)
