In Space, nobody hears you screaming!
I think, there is something missing, be it postwork or Tg, that gives the image more structure.
But still nice.
Until now your Planets are a bit like in Star wars (wich doesn´t mean a bad thing) - each has its special typical look, yet without the diversity of, let´s say earth for example.
No that you have twice the room, fill it!
Nice starfield by the way.
Best regards,
