I like that. Lovely expression, nice and sharp on the eyes, connection with the subject and a good conversion to B&W.
The crop is a little unusual, as they say rules are there to be broken. If you'd asked her to take half a step to her left you'd have a clean background without the dark section above her shoulder. That, with a little more room at the top (a step back from you) would have got her eyes on the horizontal third and her right eye on a vertical third. If the last bit doesn't make sense, Google rule of thirds.
Very competent shot, way better than my early shots. Well done.
