I took a slightly different approach. While undoubtedly "your lady" is indeed beautiful, I felt that the picture didn't do her full justice, so to speak.
First my "reasoning" (such as it is..lol):
1) Because her body is straight up&and down and in no real "position" and because her clothes are not designed to draw attention or otherwise remarkable (typical winter-wear that we all shuffle around in), the body is - photographically speaking - immaterial. This, I think, is also what photoj picks up on when cropping the way he did.
2) She blends in too much with the background and doesn't stand out as much as she deserves. She is the focus of our attention - or should be.
By that token, her face - what little we see - is really what makes this picture of her. On the other hand, there is not enough picture to simply focus on her face alone and you did not pretend to make a portrait either.
Here's my interpretation:
1) Bring her forward in the image by making the tonal range a little more dramatic
2) Get her closer to the viewer - in this case by cropping
3) Realize that this will never be a portrait, so include enough of her torso to show her somewhat "whole"
4) Sharpen her - especially the facial region - to appreciate that direct stare she directs at you
5) Shove her to the side - thus making it more "deliberate" compositionally.
6) Apply a frame to guide the eye a little more and to combat some of the distracting elements in the bacground - there's a bit too much going on and it at the same time, not blur the heck out of it.
So this is my version of how to implement these elements, to offer an alternative to photoj's excellent perspective.
