It aint bad. The smudge behind the planet kinda kills it for me. Theres so much more you could do to this

What do you mean by smudge? I didn't use smudge for this, and why would I use smudge on an originally 3000 pixels or so image?

nice atmo out there broh....cant figure it but i think the rock formations @ the lower left portions lacks depth, liked high lights from the source to add definitions &  exaggerate depth in the foreground. middle & back ground...coz you have an intense high lights in your focal w/c is the planet & no other HL in your adjacent rocks formation...other than that i think your piece is great...keep up broh!!

Finally some constructive comments, unlike that biggot Dean...
Yeah the lighting is kinda off on the asteroids but meh, better luck next time eh?

This looks like a great start. My advice would be to work on the lighting and make it more dynamic and not so white. You also might add in a few astroids or a planet up close with a blur for some depth.
