Aye, I agree with what's been said, and hope you would add some more water and some spray, or foam? It's easily faked with terrains and an appropriate foggy texture... Another cool thing to try would be a large volumetrics cloud sphere with a radial light with a gel on it inside the sphere. It can produce awesome, totally unforeseen cloud types and gives you a lot more control than the Skylab clouds, which you can also leave on! If you set the volumetric material to "Sky Integration" and your spherical cloud base will take on your sky's coloring, it's very cool!
