I'd guess that you've perhaps pushed the outer stuff pretty hard, and also noise filtered it. That's fine, and correct, but you need to protect the bright inner stuff to stop it getting burned out, posterized, and blurred in the process. Suggestion: produce two versions, one exactly as is, and another processed just to bring out the sharpest detail in the "iris". Then use PhotoShop layers and masks to combine the two, taking the faint outer features from one, and the bright sharp inner features from the other.
Best,

Mike,
Ok - took a while to get to back this but here we go.
Revised processing to add more contrast and detail to the OIII centre section of the Iris. it's an even more realistic looking eyeball now.
I hope you like it, thanks for the tip.
