Awesome shot! I see what you mean! Very cool!
I have been trying for some time to take a photo and get really sharp eyes so I tried using the dodge tool and got an interesting result.

Unfortunately if you use Portrait Professional, it will sometimes do this to eyes when you DON'T want the effect, which is why I don't use it much any more!
Nice! Is that a reflection of the photographer in the catch light?
