The look nice for the most part. However, I have a problem with the lens flare. They both look unnatural. If they aren't in the back, I suggest smudging them + moving them to the back. If they are, smudge them + blur them + opacity lower.
They're nice. You could start to add some more details, nebulas and other galaxies would look cool. Maybe a bit more black rather than shades of blue/pink.
