This looks very washed out - either overexposed or lightened too much in post-editing. With some levels adjustments and neatimage, it would look pretty good.
There is too much noise in this image which degrades picture quality greatly. Also, the water is the main subject but seems too dark and to get lost in the buildings. I would have preferred if you'd zoomed in on one of the fountains and tired to capture the light reflecting in it than the big scene you've captured.
The colors in this are gorgeous, and I like the use of line. It seems like there is a lot of "noise" in it. (This may be my monitor, but I am not sure.)
Cool picture.
