nice compositon, a bit much empty space in the lower part maybe.
light is complicated in a shot like this. so the scene outside is overexposed and lacks contrast a bit. two exposures combined could solve the problem, or maybe even photoshop can still rescue it.
the whitebalance outside seems a bit off, but i like the foreground colours
Very interesting composition. I would like to see it with selected colors; say through the windows with color and the rest b/w.
I just thought that might have an interesting look.
I like the image you have captured.
