Your shot has the sense of having been "caught" or found which I really like and the warm light gives a sense of calm (the user doesn't feel like he's been caught doing something bad).
She is beautiful model. Somehow I think the focus is on her brests. I would try to focus more on her eyes, as it is always essential in portraits. Lovely warm evening light. Good perspective, nice composition.
She does have a classic beauty about her. Good composition. You may consider color correcting for the yellowness caused by your main light's color temperature. Good job.......
