I love complex parking garages, it should be its own style of photography- lets you show off the contrast, concrete texture, words and vertical lines. Very Nice.
I'm going through the entries, stopping at those images I feel have had the benefit of an unconventional eye and dwelling a little longer to try to see and appreciate what you saw. This is one of those images.
Positives: Standout tones draw me in and then the sign stops me in my tracks! What fabulous light you have found here. The aspect ratio is perfect too and the various beams add much depth.
Critical stuff: There's only so much interest to be had from such a scene (though I think you have found much of it).
