There's a lot I like about this shot - the location, the tones. And the model facing away from the camera works well with the overall mood of the image.
I like that you didn't center the walkway in the frame, but (nitpicking) I feel the image is a bit too biased to the right. You have the walkway on the right half of the frame, and the building continues off the right side of the frame (and has a doorway or window off to the right of the walkway). All that could still work for me if the model hadn't been as far to the right as she is. Yes, I realize she's not actually that far off the center of the walkway where she is standing. But with the perspective of the sides of the walkway, the right wall disappears into her hip while, in the distance, you get to see essentially the full width of the walkway to the left of her, which over embellishes the feeling of imbalance. It all just combines to make me feel like my eyes are being pulled slightly off the right side of the frame. Had the tree on the left been a little more defined, or had the model been a bit to her left (maybe even just left of center in the walkway, but still well to the right of center in the frame) so that the far end of the walkway was more balanced around her I may have enjoyed the shot just a bit more.
Again, nitpicking, overall this is a very nice shot!
