The angles of her legs make them look heavy, especially the back one. Also she doesn't look comfortable the pose overall doesn't work. also feels as if the light was possibly too directed at the bench and not enough at her, I'd like to see her lit more because the yellow of the bench is drawing my eyes away from her.
She is an attractive girl and that location is something I would love to get my hands on but I think it will be better with tighter light control and a bit more moodiness.
Chaos, panic, and disorder .... my work here is done.
