A very nice shot ... try cropping a bit tighter and moving her out of the center of the shot to say 1/3 right. Your depth of field is very dramatic, i think with the crop adjusted this shot would be awesome ...just my thoughts
Good luck
Nice capture. I think i would like this even more if it were cropped in closer (get her eyes at the top 1/3 spot and lose most of the dead space on either side of her).
I like the idea of contrast.. dark clothing, dark hair against a brighter background. It puzzles me why you didn't go all the way, why is the upper corner dark? It causes the hair to loose its impact, while it helps the photo to eject a very energy-rich feel. She's smiling, looks like she is moving, engaging us actually and the hair helps shouting out 'energy' but you loose quite a lot of its feel because you break it by that one black corner. Why?
Otherwise, love the lighting and the feel you have captured here.

sweet picture, great hair. A pity the background is not more even. As it was advanced editing perhaps you could have got rid of the black area top right. then nothing would have distracted from her face.
It's a nice portrait. Shame about the black areas in the background. They are slightly distracting. I love her hair against the lighter parts of the background.
