Mad Max.. IN SPAAAAACE!

I'm trying to envision a post-apocalyptic Mad Max style universe but spread across a dead stellar empire, so instead of cars people are getting around on starships and trying to exist across hundreds of dead and dying worlds, moons and stations.

I'm trying to find an art style that suits it but other than straight forward wacky out-there standard Mad Max weirdness IN SPAAAAAACE! I can't put my finger on a specific style.

Do I really want that Mad Max look, or just desperate survivors in a sci-fi hellscape looking to survive? Do I decide on an aesthetic first and then break it down to how it would look after a major collapse? How about Star Trek but all screwed up? Or a devastated Expanse?

I just can't get a visual. I know what I want to from the rules for the skirmish wargame, the starship battles game and the tabletop RPG side of things, but I just can't get a visual design down.

I've only just designed the game, to be fair, but I usually come at these things with a specific design in mind. This is what happens when you have a bonkers dream on the Saturday night and get up at 6:00 on the Sunday morning to get 4,000 words down to exorcise the ideas I had. I rushed into it, I think, and thought more about the concept and the game mechanics than I did about the overall package.

I want to complete the rules and get them playtested, and for now I'll use the 'Mad Max IN SPAAAAACE!' tagline to get my basic idea across. I'm sure the overall design and look of the game will come later.
