Good looking submission. It seems well thought out. I like the fact that we have an act progression outline that is exactly the type of stuff that I want in a module.
Just spending one panel on the ship layout is good, most similar modules spend two or the full three panels for a map that isn't really relevant for the scenario.
A very minor comment I have is regarding the decompression levels table I would have put the title of the table and the O2 remaining in a header as part of the table itself. Also not sure if the sealed unsealed distinction is necessary, perhaps it could be kept by saying that sealed compartments keeps O2 for ten times as long as unsealed ones.
