This is funny, in a game I'm making called Adrift, the ship you're on is rapidly approaching a planet called Dau Vatu, and this looks oddly like said planet from a distance. Only thing is Dau Vatu only has one known moon.
its beautiful, and it feels i've never seen the colors before. i think the starfield might need a little more work, though. I suggest that you add you reduce the amount of small stars and add some larger stars (but not too many!) with focus below and above the planets. But still i love the atmosphere and the colors! I hope i helped, and the part where i suggest you to place the larger stars above and under the planet is only my personal taste.
