Architecturally, this looks like and interesting building. I like the colors, but compared with other entries in this challenge, the overall photo doesn't hold my interest as well.
this feels more like an entry for "reflections without mirrors" than the current challenge to me. lovely colors in the photo, and i would have liked to see the shot taken just a wee bit wider to allow more of the diagonal lines to flow through the photo.
For me this does not meet the challenge. Yes, windows are transparent, but in this case the viewer is not looking through them, but instead there is a reflection in them. Better for the "reflections without mirrors" challenge than this one. However, it is a very nice picture (i love the blue and the brown/orange), so that saves you from a '1'.
