Who killed Milly Bennett?

Who killed Milly Bennett is a short film I produced for my Final Major Project in College. There was no set brief but I had to Pitch the project to a tutor and show him various drafts to get his feedback. I took on a lot of Major roles for this project including Pitching, Script writing, Director and Editing. The Original Pitch for the project was: "A young girl is murdered. With everyone having a clear alibi, two officers must stop at nothing to find who killed Milly Bennett" An audio commentary was also required for the grade which I have linked bellow Feedback was good but I was told the sound needed more work and I was too negative to myself and the project in the commentary
