A little astonomy-scene. I have worked 45 minutes
Not bad for a 45 min scene. 
Nice mood.
Crits are:
There shouldn’t be stars visible in front of the sun (and near by)
The left planet looks a bit flatt and it’s not clear where the light should come from.
(Are pics in the signature allowed ? Not sure about this)

Yes… But can I edit blenders stars in the background texture?

I see ist. I have got also a problem with the light. I want, that both planets are a bit light. If I put the light exactly on the sun, the planet in the front is only dark .
I have erase the picture in my sign. Sorry 
The stars seem to large to me. It doesn’t look like a finished project to me but more like a good start.

maybe you could use two lamps and angle them on each planet?
that yellowish glow I think is a bit to much
I recon the sun looks like it is emitting abit from the earth.
Also i think the panet closest to camera needs texture
Its very good for 45 mins!

you can configure the star distance from the camera, so just put them futher away so that they will be far behing the sun.
and the start do need to be a lot smaller, and maybe different colours (start rn’t all the same)
mystery
very nice for 45 min!
