I don't know if this helps, but I would try making the aspects of the eye texture more structured.

-dark rim around outer isis. soft and blended.
-light halo just outside dark rim.
-keep red to the corners and away from the iris.
-add halo of dark around the eyewhite
-less saturation in eyecolor. Less cariation, smaller scale of detail
-crisp highlights on cornea. Look for dots of light.

Hope that helps.
