Questions for Myra

First Draft of my piece:

http://www.youtube.com/watch?v=BIIH7wDh3L8

This is my first draft for my film trailer. Some questions on it i would like to ask are:

1. Do you think the music in the piece goes? Should i cut any of the music or add some more?

2. In the scene where the girls are in the bathroom, do you think that needs music or anything changing?

3. Do you think any of my shots should be cut or changed?

4. Is there anything i could change, that you feel would massively improve my trailer?

5. Do you feel my piece represents the age restriction to being a 15?

Thank you, your answers will be of great help.
