In all honesty, that's not really a "Professional" picture.
The depth of field (I think, correct me if I'm wrong), wasn't used properly. The focus was on a few debris, when it should of been focusing inside the hallway or at the person. The build is unique, however the fading off into oblivion part shouldn't be the sharpened part, it should be the blurriest. Maybe you could use some intersection of thirds, and have the bloc head slightly to the left a little more. maybe some more detail in the build itself.
The build is good and unique, but the picture obviously could be worked on.
