Looking for tips on drawing textures

I wasn’t 100% sure where to post this, so I figured this would be the place. I’m trying to make a Moon Base Simulator and I’m working on a background texture for the surface of the moon. Something that can be tiled easily.However, I can’t seem to get anything to look right. Here’s the menu screen for reference to the art style.

(And yes, I know how to do screenshots properly.) Any help would be greatly appreciated.

The easy way to do this is to paste a texture Into a canvas twice as big in both dimensions, mirrored so the same corner is in the center.

It doesn’t even have to be tileable. I just want a texture that looks reminiscent of the moon and follows the same ARt style
