This is the first version of the space station for The Wandering Earth. Rather than going with the full rotating ring, we made a stick with counterweight at the opposite of the control module. The crew was rather small at that point (really early in the project). It was then completely redesigned by another concept artist in another team, and I must say, it was better than my version. But a lot of the details survived, as for the command center and the general organisation of the space station.
For the interior drawing, I did a model of the space and then made a lineart detailing the space (with the help of ZHOU WENTING). The fully rendered version was made by WANG DI, who is the queen of detailing complex scenes.
A lot of the drawings on The Wandering Earth are collaborations and has the team lead I overviewed the whole design package and process.
