That looks much better! It's an awesome scene :) Did you try out the ground fog
version I posted? It doesn't look nearly as good, but I wanted to provide the
option for it anyway.

Media would be the ideal choice in any case, but it's still pretty slow even
with multiple cores.

In other scenarios, casting glare from the sun would also help balance the
light. A sphere with a polar or spherical pigment pointing at the sun works. And
there's that clear tube with a specular or phong finish connecting between the
sun and camera. It seems to work pretty well, and even reacts when something
occludes the light.

And then there are clouds. The same technique of using a polar pigment located
at the camera position--and pointed at a light_source--can help "stacked planes"
clouds look more realistic.

P.S. Are coral snakes desert creatures? I heard this saying regarding the
distinction between coral and king snakes: "Red touching yellow, kill a fellow.
Red touching black, friend to Jack."
