I'm doing a study on eyes. I knocked out this one today, its by no means spectacular, I was working more on the shape than anything else and its way too much dithering but i like to think its stylized. Constructive feedback is welcome!

I used this as the reference image.

Next I will be looking at anime style eyes.

Feel free to post your own study of eyes. In fact I prefere it, we could share styles and ideas and techniques for who ever wanted.
