Here is what I was able to do. I added in the clouds, but they cover up too much of the planet. Everything I did with transparencies and the trans maps didn't help.

I deleted all the lights except for the IBL. I am thinking that I can create a map for the IBL of space with the sun at the far left, maybe that would do the trick. I also rendered one version of it without IDL, and it seemed to work better, as I wasn't picking up light from the whole model.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
