One of my first animations was a solar system and I had a lot of fun making it. I was recently asked to make a similar animation for someones educational project, so I said sure! The result is below, the project is finished but I still welcome any feedback. No attempt was made at realism for 2 reasons:
The requester gave some precise guidelines and they were not realistic.
I personally think that realism just does not work for space related animations.
Very nice, only one comment: I would definitely use a different font (as your current one does not match the feel of the holo like info screens). If you would use something more modern and slick (not too scifi, though) I think it would significantly up the experience again. Also, did you render it with motion blur? The rotation of the planets look a tiny bit “on top” of the background, such as in computer engine games. I do not know if using motion blur to some extend would get rid of that perception, but as your basics are all done, you could spend time to look at these details to move it up again. Hope this comment helps.
