I don't do portrait photography at all, so in some ways I'm not qualified to make this comment.

If you really want critique there is one where maybe her feet our a couple of pixels too tight to the right hand edge and possibly a couple more with smiles like the first would be good to see and would lift the mood. If that's wanted you want to do if course.
