Here's a P6 render with somewhat better quality settings. With my basic settings I got some nasty artifacts on the cornea, which if I remember right if typical P6 behaviour. I think it looks quite impressive overall, but even here, the problems at the sclera-iris boundary that lesbentley noticed are still present. I don't have P7, and I'm too lazy to install P5, so I can't tell if it's just P6 having this problem.
