Thanx guys, and YEAAHH I didn't like the clouds too.

I'll add more samples next render to see what happens and push the planet a little into space (it has to be bigger in sky than moon but not so....)

There are some bucket errors(if you can see'em) too that I'll try to fix and wanna put some mood in the overall image (any tips?!?!). I thought about some kind of desert sandstorm but it wouldn't come up the way i want (more fluid and windy).
