Musical Theatre evaluation of monologue

My monologue was called 'The divorce'

We were all given a monologue each to annotate and learn as homework as we were not allowed to rehearse it in school. My monologue was performed and filmed in the normal performing arts room. Here is the link to watch it. - http://www.youtube.com/watch?v=_yW6-zGVkg8&feature=player_embedded
You can also find it on the KLS performing arts blog.

My monologue was about a girl who has just found out that her parents are getting a divorce. When I read through the monologue and annotated it, I found that the character calls her dad 'daddy' so I thought that I should make my character a daddy's girl and then make it obvious when I'm not happy with him by raising my voice and not letting him confort me. To make my performance more believable, I imagined that my parents were stood at the front left and right of the room, that way I could make it seem like I'm talking to them. Pretending that my mum and dad have just told me they have got a divorce made me get with my emotions more so I could act more upset and angry. Therefore by the end of my performance I was throwing my chair across the room.

I felt that my drama piece went well and I enjoyed rehearsing it on my own and making it 100% mine.
If I were to improve anything it would be that I carried on my anger at the end to make it more powerful.
