I feel this would be nicer if there was some more light defining her shape. It's ok and desirable in low key to have areas that highlight shape. This picture could be lightened up quite a bit and still be low key.
rather nice, but you should try to submit a bigger photograph next time - there is an article in the help section, nice photograph, a bit on the dark side though and a shame it is so small.
Please remember to make the longest side 640 pixels. you have used 447x292.
The composition and lighting here is very good. The softness is a touch on the heavy side, but it works. Pushing the light up just a hair would allow you to use a slightly faster shutter speed if that was a limiting factor.
I really like this pic. I just wish it was a bit larger.
