I think this is an interesting photo, but fails slightly for this theme because its not clear what exactly one is looking through. The out of focus foreground object should encircle the subject more, I think.

beautiful shot, but the fencing is more of a bother, than a part of the shot.

I like the colors and quality of the building, but the fence grating doesn't do it for me. This is really a shot that doesn't need it (though, i realize it then wouldn't fit the topic).
