A photomanip? Didn't suspect it till I scrolled down a bit and read it. Well, in my opinion, they're some coloring issues. The inconsistency of the level of contrast throughout the entire piece is a major distraction.
The contrast is fabulous! I also like the perspective and the focus, which isn't concentrated only on this bollard, but it seems to be everywhere and see everything In fact this photo reminds me of peaceful holidays spent in a really nice place without crowds of tourists.^^
