hi headbirth,
A son of Zeus? 
A good challenge for sure.
I would like to point out some recent Water threads you might like to take a look at in the main forum…they might give ya some ideas.
I, myself, have been wanting to delve into this a bit and will try this weekend to play…I have some notions to try with some very little known even less used features of zbrush that I think I can make work for some interesting results…whatever they may be …it will be fun experimenting and if I get the results I want, I will definitely post up mats, lights, and a tutorial.
But first and foremost will be the next newbie challenge. Then and only then, I play!!
