For one thing, I suspect that most voters vote from a technical stand point as opposed to an artistic one which this would fall into. I'll focus on that aspect because I quite like the idea of the picture.
The black area at the top makes it look like you had an error on your card and only got three quarters of the file off it. The guy has a doorway coming out of the top of his head.
I don't think the narrative is strong enough, perhaps he should be further away from the camera. An alternative might have been to move to the left, you might have got a little bit of profile and/or his reflection in that window.
It's hard to be your own critic especially when there's an image you emotionally invested in. It's all too easy to see the picture that it is in your mind as opposed to the less perfect reality.
Take heart from this though, because you are definitely moving in the right direction.
