Excellent use of desat here! Makes a great abstract. I am thinking (if you had any control over it), the guy wlkaing would look better standing about where that puddle is just upper-right of center. Nice job!
My only question for you is did you desaturate this or is this natural colors. It is a very cool shot! Love the leading lines.

The stairs are painted a blue color but not as vibrant and bright. Desaturation of all colors except blue/cyan. Boosted saturation of both blue and cyan. Also went into selective colors and adjusted both blue and cyan until it was vibrant.
