It's not that great, but I love how you actually tried basing it off a real space station, kudos for that! Yea you should try making this in a space map.
Some things you can do to make it more realistic:
- Make the modules connect through small openings
- Add vertical modules so it's not like a regular building
- Use slightly different lengths for the modules
- Add a truss! This really makes it look cool when you put solar arrays and stuff on it
I also sometimes host a space station build server, I'll send you a PM about it if I host it again. We had a really neat space station that you probably would have liked.
