I agree with TC, the one on the right looks much more natural. But still very dark, not sure if thats what you are going for, perhaps try a lighter shade of each color?
I hope when you say making the water move you mean in waves and not just the ripples in your material, because it's hard for the water to look real when it's flat as far as the eye can see. Maybe try throwing in some larger waves to break up the flat surface using displacement maps, or just modelling them into the water object.
