Also, I don't know if you can see it in the Beach render, but there appears to water(?) running down the skin around the right eye (tears?), and froth(?) in the right corner of the mouth.

The results of VSS are really interesting. My character has a whole new look (and no nostril glow!) ^^
Are you thinking of making shaders for different types of skintone? I could help with pale Asian (Winter, high contrast, saturated) I am really picky abut color, (that's what started me this character in the first place! ^^; )  The character above is inspired by a real person and I have reference photos for skintone under various lighting situations. If you are interested I could post some examples. 

p.s. I made a mistake in my labels on the Top Right picture, that was done with the same lights as the top left picture. Surprising, right? All that yellow was not the lights, but the shader? oO
