I used Nerd's free eyes for quite a while and they were pretty good, except that pupil tended to look milky in some lighting. When I got Cake1's Real Eyes and did a side-by-side comparison (put in one real eye and one of the free ones, same texture), I just about died, Cake1's look SO much better. I wish everyone who offers eye props would do that. I would have bought Cake1's months earlier if I could see on one face, right next to each other, the difference. Trying to guage from sample pics without a base comparison right next to it just wasn't working for me. I couldn't tell how much was texture, how much angle, and how much was really the eye models.
