This is ridiculously good, and is right up there with Garot's Cover of the Month-winner for Das Boot when it comes to breathing new life into a film with very few available designs.
Whether it's a matter of "zooming out" a tiny bit, moving the crashing wave down a tiny bit, or making the back dirt road a little more saturated to differentiate it from the splash (or decreasing the semi-shadow you have down there so that the water is more white instead of gray?), anything you can do to further define the elements would be icing on the cake of the outstanding scene you've built here.
Also, you've got a really nice sky... what if you decrease the size of the stars by about 12%, then let the actors' names be on a single line up top? This could also allow you to move the whole design up a little bit, so that there could be more of the water showing.
