Better to be open to the community and help others achieve what you have. My guess is that the windows are a flat texture, not tcGen env or anything fancy like that, since the windows down the street at a 90-degree angle from the ones on the facades of the buildings are identical.
On that note, try taking some glasslike black and white image and add it to the windows with the line "tcGen env" in the shader code...you'll get a cool half-reflective effect when you walk by.
Other than that...looks pretty solid. How extensive is the street layout beyond that one alley? You might also want to play with your lighting a bit...that light spot on the wall doesn't look quite right in conjunction with the beam shader.
