All those lines, all those structures and shapes seem perfectly in their right place in the square frame. Personally I enjoy how I seem to be able to look at this and perceive the depth and 3d space in the image and at the same time when I look less 'consciously' I see a wonderful abstract and more flat image with beautiful shapes.
Nice one, the proper B/W conversion helps too by the way.

PS suppose you mean a 50mm on a FF camera ?
