Eyeball Practice

Okay, I've been searching for tutorials on how to model eyes, especially eyelids, in a cartoony sort of style, and it was pretty hard to find them.  Most tutorials I came across show how to do more realistic ones.  The one I ultimately decided to try, that was the closest to what I was looking for, used NURBS.  Instead of using all NURBS, though, I used a polygon sphere for the eyeball and converted the NURBS I used for the eyelid to polygons.  Then, I just duplicated that and scaled it -1 in the y-axis.
