Just watched your film. I loved your styling and characters, it was very entertaining. The green screen looked good - I wouldn't have ever guessed it was done with a phone. Something that improves a lot of films is foley. I thought this film could have definitely used some stock sound effects to break up the constant music - like when the soldier was flexing and the gun being cocked.
All in all great job. I think story wise your team has often nailed what you're going for - if you keep improving the technical side you'll be unstoppable!
