Overall you've done a nice job , there are a couple of things you might like to have a look at. The man sitting on the edge of the pond (left front) is obviously an alien he has two faces, three arms and a dislocated foot. The water behind the two ducks on the board, shows a bit of a line and a mismatch with the lighting and water texture, there are a few other small areas of water with similar little issues. I know we are in vote only mode, but these are a few things to work on, because it is a very nice pano.
