Well, it's mostly elemental-based--fire/water/air/earth. I would like to see it fleshed out--we have so many 'skinny, lightweight' religions with little material. Cren, why don't you simply add whatever material you have to an existing religion? "Mother Nature" could be one of the Earth Gods.
We basically study nature, then attribute various phenomenons to (most unnamed) gods.
ex: Why do we have tides? Because a god creates them. Alright, now we can study why and how this god creates the tides so that we may better understand and exploit them.
