Looks fantastic. I would like to see her head further down in the frame as well. Even though it's not meeded because it's a great shot it would be interesting to see her hair flowing out the back not in the mist as well (like her face). I would love to see it. I really like this shot and a nice model as well.
I think the overall composition I like.. but here face seems a little too disconnected from the background maybe. good work blending the clouds over her arms and chest. i would prefer that the top of her head not be chopped off i guess.
Love the background and the tones. Really like the composition too - interesting choice of crop on the top (not exactly sure how I feel about that, not being able to see any other options). I'm not crazy about the transition of the model to the background on the edges of her sweater/top. The lines don't seem to meld with the flow of the rest of the image IMHO. I know that "harshness" goes with the overall feeling of winter and theme here, but not sure that it translates well in this particular area. Just my opinion - and you know I LOVE your work. The transition everwhere else looks great and I love the cold mood. Great use of lighting and color.
