Very simple pattern, but quite pleasing. I like that the shadow is what I see first, and then the same pattern in the railings (which makes sense). My point is, by seeing the shadow first, there is a sense of peace about this shot. I feel at ease when I see it.
Great job! I have seen so many people mess up this type of shot, but you nailed it. Everything is in focus, it's well composed, the vanishing point is right on the horizon line, the colors are vivid and there is nothing really distracting in the background. I wish that building on the left weren't there, but I'm sure you would have thought to remove it if this was not a basic editing challenge.
