Your's looks nice, but I see a shift in skin tone from before to after. Did you make other adjustments? It looks like it went from pink to yellow in tint.
My simple method for eyes is like so:
use quick mask mode with masking the selection and not the rest of the image
use a brush with about 20% harndess and paint the iris and pupil area
switch back to normal mode from quick mask
apply usm to the selected eyes (150%, 1.5, 8)
I vary the radius and threshold depending on the iris color and sharpness of the original image and the effect I want. Works well for me
Really cute kid and capture too!
