Tryst I honestly couldn't see doing the skin without an airbrush. Nevermind the sheer time involved with layering that large of a surface area perfectly, but the actual skill involved is well beyond me. For skin colors for the girls I really prefer the Rosy Skin triad from RMS, with medium fleshtone from VMC (not the sunny skin tone, holy crap is that yellow!) mixed in, then coming back with pastels to finish the shadows. It gives me that paler, almost cream color skin I see alot on anime, except with a little more depth and realism (though my photos don't ever show it!). If you don't have a reliable airbrush, I do not envy the task in front of you!
