Here is the rejected options for the space station.
They started with movie magic gravity which made me cringe a little,
first version was an assembly similar to the ISS, with small tubular modules making the interior.
second version had a central hub which gave me space to the actors to interact, with an access hatch in the ceiling. Just because!
I made a sketchup model of both those options and a line drawing to get the idea across, but the final render was made by ZHOU WENTING ( https://www.artstation.com/zhou2014 ) and WANG DI ( https://www.artstation.com/adiwang0326 ). They made a fantastic job breathing life into my technical sketches.
Thankfully it evolved in a more realistic version, I'll post it next :)
