Planet Explorations in Blender

I bet there is a similar planet to this in the universe :)
These are some test render, project are still wip.
All textures are procedural.
I EVEN made the lens flare effect completely procedurally with compositing in Blender 3D.
Clouds are still look so smooth I couldn't solve it, if someone has any idea please contact me!
