If you want me to be honest, it's pretty bad and snapshot-like.
Discounting any sentimental (this is a wild guess) reasons you may have for shooting this, the lack of color and general monotony of this photo is glaringly obvious. Maybe you might want to shoot a little higher and include something else next time.. Other than boring water (if only it was more colorful, or had some reflection, perhaps) and floating balls..
Besides, I note this really distracting thing at the top left corner. =/
