The gravitational force of so many planets in considerably close proximity would cause the planetary bodies to collide with each other in an absolutely prodigious manner.

Aside from the nerdy stuffs, I think you need to try a shot that doesn't reuse the same buildings multiple times and show some consistency with lighting. Also, not nearly that degree of space would be visible from ground level at morning. More nerdy stuff but, still, it gets me.

Planets and stars themselves look really nice, though.
