Right Nance, the highlight is the important part, but I think the outer layer needs a texture as well or you'll end up with just a 'wet look'...which could be usefull in itself.

Not sure what 'Real Eyes' is, but I know Vicky and Mike have an Eyeball material which is a second sphere layer that covers the eyes. You can use it with highlight set to give the eyes a kind of glistening look.

I'm gonna have to play with it a bit too...I just have so much to play with this weekend and I'm sure it will be over before I know it as usual.
