This is not a criticism, just an observation: it looks like what I imagine an ocean of hot corn syrup would look like (after dyeing it blue). The viscosity seems right; possibly the surface tension is not what ocean water would have (a colloid of salty H2O and biomaterial, which is common in real-world experience but quite ugly for computational fluid dynamics).

Also note that the ocean spray here is a post-hoc effect, but for a real ocean the spray dulls the sharpness of the waves in a way that will be (vaguely) apparent visually.

Of course there's almost no "physics" in this elegant, simple, and highly effective model, so I want to emphasize that suggesting directions to poke around and try things should not be construed as an armchair criticism.
