"Gravity" movie - Airlock concepts

Chinese space station airlock concepts from the movie "Gravity". [spoiler] - This is from the latter part of the movie, where Sandra Bullock's character manages to reach the space station using a fire extinguisher (which I've also included here). Unfortunately very little of the airlock was shown in the final movie, as a POV shot was used as she entered the space station; instead we were given a very close-up view of the pressurisation valves as she turns the oxygen back on (which also went through a few design iterations - I've included a few examples here).

Modelled and rendered in Cinema 4D. Decals and graphics created in Illustrator (please excuse my poor Chinese translations!). Compositing done in Photoshop.
