Hmm! I'm not sure that forcing someone to look at the reflections was your best choice. The windows are your primary pattern, followed by the power lines and any reflections would be the tertiary. By forcing us to look at this backwards (which is what the title does), we actually see a lot of stuff that detracts from the reflections...namely the wires, the shadows, even the light play within the shadows. I bet you get tons of comments about them.
Perhaps taking this at a different time of day would brighten up the building a little. I do like this though.
I have to admit I might have overlooked the light patterns if not for your title. Pretty good color, exposure and details showing, but the composition of the scene is not really drawing me in.
