after one such devastates, I think water should have more waste on the surface and the reflections of the sky and especially those of the sun, should be more important. otherwise the rest is very nice.
I like very much.
good job ;)
I like the serene feeling of this and the "Paris" colors of the sky.
Amount of waste may also depend on the time - how long ago did this happen? ;-) No disaster marks on the foreground coastline and even some bushes growing there, may indicate that it was some time ago. Anyway, some waste (or boats?) on the surface may give nice reflections and shadows.
If you still want to work this, you may try remove some of the bushes from the right foreground, so that we could see the coastline and path to Eiffel Tower better - it might add some depht.
Some cloning of left side of the sky is pretty visible. It might also be a bit darker.
