One thing has been bugging me about the spacesuits. The hands of the suits don't have any fingers. It's hard enough manipulating things on Earth with mittens on. It would be dramatically harder doing that while weightless.
It's just generally hard to do stuff from a space suit. That's why most stuff done in space are done in a pressurized cabin; space suits are only used for EVA.
As for oxygen supply, it's a little thing called conservation of detail. The audience usually doesn't care about that sort of thing, and it's practically irrelevant to storytelling, so drawing it is essentially optional.
