Looks good friend. My only suggestion is, the clouds on your smaller planet look to be way too high off the surface. I would lower the cloud layer and make the radius only slighly larger than the planet. Everything else looks good.
Thanks! I'm not sure why it rendered like that, the radius of the cloud sphere is only slightly bigger. I did another render (same radius settings) with the sun in a different position and the clouds came out perfect. I can't figure it out.
