>>8644743If you don’t mind suggestions, I’d say putting a row of modular “shops” lengthwise, facing the shops you already have. That way you can take pics down the street in the middle, or create little alleyways between the modular shops by spacing them. It’ll also let you remove those buildings for whatever need you have.
Aside from that, I’m partial to the cyberpunk look, so I’d say more neon signs, billboards, posters, graffiti, trash and grime. Also some paint details to make things look a bit more lived in.
But if you’re going for a new space station look, that might not be what you’re looking for.
