She's an interesting subject, but the light is extremely flat and cool. The lower half of the background does not separate well from her outfit, either. In that location, and with her fairly dramatic "look" I think some boldly colored clothes would work better. If not that, place her more completely against a green background.
The foreground is downright unattractive.
She's quite nice, though!
Try her with some more directional light, with a little more attention to the stuff surrounding her. You'll be great together.
