Very interesting play with the given light, I quite like how you put the one person in your photo into a state of "anonymous", but I feel there is too much dead space around window and mildly lit table with glass. The reflection on the one armrest protruding into your frame from the bottom is also quite distracting. My guess is that this photo would increase its impact if you cropped in from the left right up to the light, and if you want to stay with standard print sizes in from below and above until you're back there.
