Agreed, Kaempfer, this was a fun set to use. ^^ This is very pretty, I like it. You might want to hold down Shift and remove the water tile edges around the sides and tops of your buildings and statues. Just a suggestion, would make it look better, imo.
I know I'm several months late in replying here, but I'd say leave some - if nothing else, leave the stuff around the statues at the bottom of the image. In that location, and around the small island with the broken pillars, it adds an enhanced depth to the object - making it look as if, just perhaps, the water level used to be lower, and the objects in question raised up a bit.
