First Cut feedback

After viewing my first cut, the class and teachers have given my feedback, as stated below:
1. I need to either re-shoot or over dub my bridge scenes as there is too much background noise, making it hard to hear what the actors are saying.
2. I need to make the telephone conversation more realistic by recording the sound of the voices through the telephone.
3. The pace is very good, as lots of short films seem rushed however this is not and has good flow.
4. I need to make some parts of the sound louder as it seems to quiet.
5. I need to correct a match on action error in the last bridge scene.
6. The falling off the bridge would be more effective should it be in slow motion.
