Pretty good pose you got from her there Bob. If you do a little bit of a dodge + burn in the eyes you could get slightly more vibrant colours ! It looks like you did some cutting on the shadows in PS ? There are a couple of areas I can see where you have cut / cloned / changed something.
EDIT :-
Hey Bob, here is a website which has a quick and easy tutorial on how to enhance eye colour using PS.
