What terrain features should I add for a moon style map?

I have a moon map going, and I have the basic terrain down, but what things should I have. Right now it looks pretty barren. People need to hide behind things like trees and other cover. I just want to fill up the land a little bit with "space trees" or other features of the sort. Suggestions? Thanks.

i suggest adding craters or maybe space stations

The entire map is like you are in a giant space crater, but yeah. I will add those. I was thinking more precise like what should I make some ground cover out of.

Potatoes... No, this is not the dinner... This is a map! A diner map? No... A space map! Then add potatoes! Wait... It aren't potatoes on minecraft.. But what with that potato on the 2nd map? Maybe the talking potato was a space potato!
Make the revenge of the potato! But it was the potato that killed the other two... Killed Vareide... WAIT! It killed Vareide! It is a evil space potato! Wait, what was we talking about?

Broken spaceship and station. Alien ruins. space garbage. some kind of dead trees. underground caverns.

Will add. Thanks

Add what? The potatoes that guy talked about?

How about a big volcano somewhere?

Make big bumps in the moon's surface using endstone.

Yeah, and like said above, craters and things

From here on out I will "like" any idea that I will add.

Maybe a cave sort of thing going through the moon with lots of caves cutting through to different places, but it starts in one place and ends on the other side of the moon?
Of course the map is flat probably, so an area that goes lower than the rest with a cave going through and stuff like that.

Sponges (Cheese)

? Whata heck! FIRST A GUY SAID SPACE POTATOES AND NOW ANOTHER MAN BEGIN TO TALK ABOUT CHEESE!

Then you will add my idea about potatoes? If not... Please not remove the like...

So u are going to add a potatoe but not bumps?

Can I ask you? What are a bump? I am a Norwegian

The reason, the map is nothing BUT bumps! Craters, valleys... I told you, I got the basics down. I'm just looking for nitty-gritty stuff now.

But I dont understand how you can add potatoes... And I didnt meant it when I said it... It was actual a kind of rage.. For nothing...

Instead of walls around the arena, a trip down into the void? And maybe holes in places reaching down into the void.
