I don't know how you're able to do those eyes. I've been trying on the Palpy and Hellboy but so far no luck; make-up is the only way to fill it in. I'll have to see some of your other pictures but these sure are terrific masks.
You have to modify your core quite a bit and also the way you sculpt the mask around the eyes. We perfected tha over the years with muliple trial and error.good luck with you masks
