I like the idea of this one... What you could do perhaps is to add some white water around the splashes. Maybe some volumetric clouds can do the trick so it doesn't look "too clean"? Also.. the ripples look a bit "square" where they intersect with the waterplane. A way you could fix this is to raise them slightly off the waterplane.. but then I'm sure you can look under the ripple, right? What I always do is raising the ripples slightly from the middle to the sides then you can make it appear more fluid
