Improving Animation of Planet

Hello,

I’m experimenting with improving planet animation using procedural and other dynamic feature. Do anyone have any recommendations or video links that could help? I’m adding the blends to this message. I created a scene that exports the background and planet in separate .exr files then I use a separate blend to composite using nodes. A frame takes about 3.5 mins to render at 720p. The render method is gpu with experimental for the planet.

Files
SpacesScenes.blend (3.4 MB)
SpacesScenesComposite.blend (3.4 MB)

This is after I played with the planet textured. I could tone down the brightness of the background and duplicate the planet in a smaller size.

I worked on the second version. I toned down the saturation and added a soft glow. Maybe someone has some suggestions.
