Looks like you lost some detail with the noise reduction, not bad, but noticable IMO. I like the lighting on the subject. A minor adjustment in curves and that faint glimmer of a doorway would have gone to black, which would help this composition some. All JMO of course. :D Good luck in the challenge.
The background is too noisy!!!
:-) Well, just to let you know that I can see the lamp-like thing hanging over the head, as well as the window frame on the left. Still, a very good idea and execution.
