The vanishing point effect of this photo is really good. (Though the point is not really vanishing, it leads right to that tower... should call it "converging lines", maybe?)
The overall colour impression of this pic (for me here) is "green" ... as in "with a hint of a green cast" ... and even the sky has some of it ... and so does that tower, so it does not stand out as much as you had hoped it would. Is that what you think is missing? The tower really standing out?
