Composition: Don't change a thing! A beautiful woman taking refuge from the cold in her warm fur coat. Sensual in every sense of the word.
Lighting: Well done. Shows the texture of the fur and you can see the model's face. Nicely balanced.
Exposure: This is the only thing I would work on. Good as it stands but, if you want to improve...
Cut the overall exposure (darken) by about 10%. Not too much.
See the fur at the top, right. Blown out. Gone almost all white. Same thing at the bottom, left but not so much.
Darkening the exposure will also give some more detail in the model's hand.
Doing this will darken the model's face a bit but you can counteract this by dodging or masking. Work carefully enough and you can probably tweak the exposure to hit that "sweet spot" where you won't have to dodge/mask.
Also try backing off with your contrast (flatter) just a hair bit.
If you're working with Camera RAW, back your exposure setting down to about -0.10 and slide the recovering setting up, almost to the top. Cut your contrast setting down to -5. Other settings as you see fit.
If you are working with a darkroom print from film, ADD about 1/3 stop exposure to your time and SUBTRACT 1/2 a grade of contrast.
I love pictures of beautiful women wearing fur. Nice job! 19 out of 20.
