I really like the riot of texture here - almost oversharpened maybe, but I like the effect. The fact you can't quite tell if she's looking at you or not quite is disconcerting, but in an interesting not a bad way. And the bench seems sort of suspended in space - also rather intriguing.
The dark area by her feet makes me think she was impatiently kicking and twirling her feet while waiting for the photo session to end. And there is the merest hint of a smile on her face. Cute shot.
