I can see that you could fantasise you beeing followed but there is something missing in the photograph to let is show. It is merely the title that makes one think of it in that way.
I love the perspective of my picture. I guess the only thing that may be missing is something to show what the context is for the title. I am assuming that it was taken nearby an intelligence agency?
I just don't see "Espionage" in this picture, nor does either seem to fit with the challenge topic. But it is interesting architecture, well composed, and technically fine.
