it looks like a crop of a much larger image to me...too much grain, a flat looking, uninspiring shot I am sorry to say...I am trying to find at least one positive, but sorry I can't see one in this shot
This was well composed, but you must have underexposed it a lot because there are artifacts all over the face of the cathedral (the many colors that are showing up as flecks of color.) They actually clear up when you convert to black and white, which might have worked better on this one.
I'm afraid that for me at least the overall green colour cast is quite offputting. The image is very noisy, too. I strongly suspect that the problem was with the limitations of your camera rather than with anything you did wrong.
