It's looking good, but possibly a bit cluttered. It's not necessary to fill every blank spot with some object or ship or color. It's space and shouldn't look too crowded.

I'd get rid of the blue nebula in the top left, those four small planets and maybe nix 3 of the smaller ships on the top center and right side.

The lower planet looks great, btw. But maybe a different color for better contrast to the text. Possibly a lighter, faded planet like our own moon

I don't know if characters will be better. That's what I'm hoping to get rid of. We have the original translite if we want to see characters.

I agree. Too cluttered.

Dump the characters, too. The bright red fireball planet is too close and similar in color to the Enterprise engine.

Keep just the large planet at the bottom and it's perfect.
