Maybe if you ease off on the shadows? To me, they make it look like webs floating above a blue background. I'm not sure what effect you're going for, but I don't think either
or foam
foam cause shadows like that...and I don't
think you get much foam out at sea until the wind is fairly high (cf. the
Beaufort scale).
Also I'd second Cranky's suggestion of having them go in one direction, if you can. Waves are formed by wind (unless you're in a bathtub or something) so they wouldn't be going back and forth...
Or not.
I like art, even (especially?) highly stylized art, to respect the underlying realism and structure. I think it adds that certain something. But I realize that's not everyone's cup of tea.
