Wow. very original. Nice balance. A lot of people would have put the line straight down the middle which would not have been nearly as effective as this.
the left of the building is very blown out, i wonder if you could have taken a darker exposure and pushed the blacks a bit to bring out the detail of the darker side.
I guess what you're getting at is that the window on the left is newer than the right. The problem is that your dynamic range is too much for the camera so the left window is over exposed and the right one is underexposed. You could use a half neutral-density filter to reduce the contrast between the two, and get good exposure on both. Alternatively, you could add more lighting, or wait until the sun is in a better place.
interesting, i like that you captured the new window with the light on it's side, further emphasizes the transition from old ('n dreary) to new ('n bright)
Interesting, light to dark and old to new for the windows. Exposure is a bit blown out on the light side - though it would be hard to get balanced. Overall not really sharp enough to have much bite. Good attempt.
Transition, at least for me, implies motion and a sense of being temporary. I don't see that in this picture. It's a good contrast between new and old, but nothing transitory about it.
