3D render Earth Animation with Blender

Please find a first 3D earth animation video I created after a tutorial from blenderguru.com (make sure to check Andrew's tutorials out, they are really great). I animated the cloud sphere so that it rotates just a tiny fraction faster than then earth sphere, thus creating the impression that the wheather moves on the circling earth west bound, adding another impression of real 3D.

The earth circles 320 degrees in 20 seconds at 25fps. This is pretty fast and if you create your own after Andrew's tutorial, you might consider this to be slower, depending on what you need.
