Changes from rough cut 3 to final documentary

I changed a few things from my rough cut 3 to my final documentary. At first i decided that it would be my final documentary but after discussing with my teacher and looking at it myself I decided to change a few more things. I added more music over the train, changed more music over what is coming next and I also added an ending because I felt it ended to abruptly. I also rerecorded the voiceover at the beginning introducing the new documentary because it didn't sound very good.
