The dress shirt is so 20 years ago. Her legs are front-and-center but they're neither doing anything nor presented with elegant simplicity. Her face is emotionless. And nobody sits like that with their hair in their face. If you want something sensual it needs to be believable. If I went home with a girl who sat in that position and looked at me the way your subject is looking at the camera, I would be far more creeped out than turned on. In fact, I'm a little creeped out right now.
