I use Liquitex Deep Portrait Pink mixed with Galeria Pale Teracotta for the basic skin tone. I also use a mix of some Liquitex reds for the base coat and for the undertones. All sealed with Liquitex matte varnish. Lips are a mix of Deep Portrait Pink and Taupe. And something that I learned from boot25 that has helped is sealing each layer before moving on to the next. Skin is translucent, your color comes from the blood underneath the skin, and he really has nailed that look. I'm working on achieving that too, but haven't come even close yet!
