This is the beginnings of a project I've decided to take on; a
waterfall. I'll be narrowing it via the Painted shader to hopefully make it look like as a ribbon waterfall. I've reduced the cloud layer glow power and strength as well as the edge sharpness significantly including adjusting the 'Y' noise stretch in the Density shader. I'm trying to make it appear as soft as I can; like one accomplishes with a camera where the shutter is left open a bit longer than normal - may try DOF to accomplish this.
Mist and water splashes will be added at the base of the waterfall once I'm able to get it to look reasonably good.
One of the projects I've noticed here that has invoked inspiration is the one created by Hannes:

And, thanks to Dune for helping get a start with this project. Any ideas would be greatly appreciated.
