Beyond Recongnition

This is my first attempt at using Corel Painter 12 and I wanted to draw some eye's. VERY dark eyes. That stare into your soul. So yea, here ya go! This is also my first attempt at drawing detailed, realist eyes. Please give me comments about how to improve them!

Also I must say that I enjoy Corel Painter however all the options produce good results with the added draw back of being so slow that the brush lags... (at least on my shitty laptop it does). And because of that I stopped about 3/4's of the way while drawing them. I was hoping to blend the highlights a little more and add some more definition to the iris.
