Are you asking for a critique about the fashion styling? If not ... please disregard my comments.
I like the look ... what I can see of it ... it just needs to be presented better, IMHO. And I do like the framing of the image ... off to one side like that ... keeps it more interesting than dead center.
If you are wanting a critique, here's my thoughts:
A lot of it's about the photography ... more than your styling, but picking the right shot for your own portfolio is very important so I am sharing my thoughts about this particular shot ... as if I was looking at it to put in my own portfolio.
With this stong a look, I'd like to see her hair down, but sort of touseled and wild looking ... not slick like this chignon. That's my main styling issue ... and probably not your work nor your decision.
In a fashion shot, it needs to be about the garment or accessory ... in editorial shots it needs to be about the feeling, more than the clothes. The way this image is shot (the basic lighting) leads me to beleive that the purpose is to show off the jacket (the most interesing piece in the picture) and this particular image does not do it effectively.
Here, you notice her legs first ... which is good for the model but not to show off the stylist's work. You can see the fur on the jacket, but nothing else about it. To be a more effective shot to show off the jacket, a pose with her standing or sitting up with her torso more visable and her legs less prominent would be better ... she still could be posing in a strong way.
To be a more effective "editorial" shot, showing a mood, the lighting could be more dramatic ... perhaps more than one light, one coming from the side and perhaps one behind her shoulder to create intersting shadows and more depth and mystery (a bonus ... you wouldn't see the beauty dish in her sunglasses, either).
Here's my site ... so you may see my work too ... since I believe that I should never offer a critique without sharing what my work looks like, too. Feel free to comment.
