For a first short, that was really good man! Found it a bit slow at the start but after the briefing bit, i enjoyed it!
I think there was a bit of problem with the lighting in some scenes, eg in the scene where they are watching TV, some shorts are a lot brighter or darker than others. Just something to keep in mind next time
I wasnt really a fan of the amount of moving/dolly shots you had (unless you were purposefully mocking many action films, especially Michael Bay then good work haha), some where really nice, but at times they felt a bit unneeded, especially in contrast with the hand held shots, jumping from dolly to shaky hand held can be a bit distracting and uncomfortable for the audience.
Audio could have been a bit better, maybe a better mic or better mix, but it was still listenable
Other than that, good work man look forward to seeing more from you!
