the sclera is the white of the eye, right?  I spent a lot of time on that first, to make it more eyeballey, but not too photograph-ey if that makes sense.  less cartoon, but not overly done?   all the eyes colorwise, will have a touch of heterochromia-esque quality, since my eyes are like that.  Green but not green.  Blue but not blue, Etc.  Once I finish it up, I'll be sure to let everyone know. 

ETA: when i was younger i didn't really know that it was unusual to have more than just one color in the eye (like have blue and green and gold)  i thought that was just a type of green eye.  lol.  I have since learned that's called heterochromia, to have different colored eyes, whether it's one eye is blue and the other is brown, or both eyes are blue and brown at the same time.  So I had to make my sims have heterochromia too.  it only seems fair.
