How the atmosphere into the water get?

Hey, look, I try to do is a shallow puddle of water and I do not know as much as I get to make a hole with a layer of the image of water out (which makes heaven when you're inside) but I do not get into the atmosphere of being under water (color, bubbles, shifting waves ...) but as I was outside.

Water is a type of floor over floor, it's more than just a picture. Here's the wiki tutorial for how to make it: http://wiki.srb2.org/wiki/Water_design
