It seems churlish to criticize as you are just starting out, but as an audio guy some things stood out.
The Interstellar title sequence music is awful and not in keeping with the subject matter at all.
Brother Come Home has some audio issues. Some of the dialogue is out of sync. I take it that a lot of the fx are foley as they don't match the location acoustics. The same goes for her dialogue which I take to be ADR as it too doesn't match the acoustic of his dialogue.
Don't take it personally, these are things that have to be learnt and will come with experience.
