Look I'm going to be honest, but also I'm going to tell you how to improve it. The problem with it is that there is no focus point, nothing that attract the atention of the viewer and that makes it seem boring or bland. No worries tho, the way to solve this and make it very good and interesting is by macking a character, in this case a ship of some sort, this is made to express the volume of figures better such as the sun, earth , etc... Then you tell a story, create a battle scene, or maybe the aftermath full of brocken ships all over. After that is done i'm shure than it will be more eyecatching to the viewer.
