Looks like a big jaw breaker.

Thank you!

A single biome planet? You know that's not possible unless it's an ice or desert planet, right?

Actually no, I'm no astrobiologist, just an artist. Also, fantasy space, everything is possible. Perhaps the ice caps freeze as green as the equatorial tropics. "How would it freeze green?" Because it's not water. "Then how do plants grow?" They are not carbon based. "How could that even-?" FANTASY SPACE

But yeah I'll look into a more diverse surface when I give this a whirl again.

Have a look at my posts. I've recently been getting into the concept and artistry behind planet making. Any suggestions? If you don't mind sharing, I would like to know how you make pictures this awsome lol.

Also, my personal comment on this picture:
