Thought I'd have a go at skin shading,this is my work-in-progress so far It's still kinda heavy on my video card and could still look quite a bit better, but I already like what I have here http://dl.dropbox.com/u/10887020/Skin/WebPlayer.html
That looks awesome. Even though the webplayer specular highlights are broken on my laptop, but then again unity 3 really, really, hates the x1600 my laptop has, so it's no big deal.
looks very convincing ! but i think you should experiment with image based lighting to REALLY get there !
