@Hal Oh, that's a cute take on the logo! I dunno if you saw the other banner attempt I posted above or if you're suggesting a change to my current logo, but I do have a finished one.
Thanks! I think I can swing that. It might also help with what @JaveCraze said about the empty space in the middle. There's a few other things I have in mind that I could put there (the Moon, a map of where they're going,) but I'll experiment with changing some character poses first before doing that.
Thank you both! I'm glad everyone's personalities come through and it's able to convey that they're dorky space friends.
