It took a while to make it look realistic. I also added a few little cool details like how the bottom of the supports for the sphere change their angle angle to fit the terrain, how there are hooks that keep the small base connected to the moon, and the working feature on the lunar tank...
I'm annoyed that on mobile I can't just click the save to see it, and have to go through the profile, but it looks good from here. Edit: and after remembering my laptop, awesome.
