The vertical lines in the background (buildings) indicate the horizon is off (tilted).. need to straighten it up.
The combination of close and distant background in the shot make it a little interesting, but the close background is a bit busy and distracting. The subject has decent background separation due to the colors of her and her clothing, and even the lightiing. It would really help to be able to see her face... that lack, is what kills the shot for me.
Framing is much better in your second post.. but the selective color is horrible! Not a good choice, IMO!
