Although I haven't been in Florence for a long time, I have fond and vivid memories of the art and the food. The city is a treasure, and your photo makes me want to revisit sooner than later.
From a compositional standpoint, the river's perspective lines send me right to the Ponte Vecchio bridge. In my mind's eye, that is the bullseye and area that most interests me. However, because of your wide angle perspective and your distance from the bridge, the bridge is quite small and less significant. The front of your photo, other than water, contains no areas that hold my interest and my eye scans over it without stopping to get to the distant bridge.
I hope you don't mind but I've cropped the image to illustrate my point. I'd be glad to take it down if you prefer.
