I would like to start off by saying that I have never seen a photo like this before.
I personally love black and white photos and that your choice to filter it this way was a great choice indeed. The windows force the viewer to pear into each and every one of them. They seem to tell some sort of subliminal secret. I am absolutely in love with the metal work. The metal rectangles as well as the shape of the building speak volumes about how it has be built. I really do enjoy the architecture as well. An amazing photo all together.
