Disclaimer; I'm very much a beginner, so will do my best here.
I think overall, it's good. Really like that you kept in the majority of the freckles. However, the freckle above her right eyebrow now seems distracting. Perhaps if a few more of the freckles were left in the forehead area, it would be less distracting.
Not too keen on the lightening of the highlights in her hair; seems too white. I'd like it better if more of the blonde hues were kept.
The right-hand whites of her right eye (left most whites as you look at the image) seem too bright. I like the brightening of the eye shadow. That by itself may may have given the appearance of whiter whites in the eyes?
There's a deep shadow under her lip; don't have a recommendation, but may be worth it to address somehow.
Thanks for the feedback! Also I don't really get what you're saying about the shadow under her lip. It's a natural shadow from shooting with a hard light source (a beauty dish) so I'm pretty sure it's supposed to be there. Is it just too dark or something?
