Some people really like the softened skin on portraits...for me this is a bit too much, but not horrible. I used to use surface blur before we discovered noise removal plugins...we usually use those to soften skin (in CS4) and then mask back in detail where you want it, cause let's face it, some people want to look like Barbie
The thing that doesn't sit right for me is the shadow under her bottom lip has been changed too much, removing the definition in that area, and changing her expression. Keep up the efforts
