I don't really need currently a water shader that looks very good from close, I need something just fine for a strategy game. your water shader is very nice from a close view, but quite repetitive from a higher camera position, and experienced also some artifacts when adjusted fog and some other parameters, maybe clip_far, I don't remember. moreover, it would require a lot of time, and more shader knowledge, to implement a really great one, and I'm not sure it does worth it...
