Did you made those asteroids yourself? I remember them from other space scenes, I thought it was one of the restrictions that you must link back to the creator of those asteroids when you use. Besides that, you really need to work on the planets, especially the centered one. It seems transparant and some fire ball in the middle of it? Doesn't makes too much sense, I'd say it's not bad but for your fifth, meh.
