Production- Re-recording my narration

During the week I have shown my short film to my classmates and to my media teacher and one piece of feedback that I frequently got was that the narration was too quiet. My media teacher suggested that I therefore re record it, using a dictaphone, which would give me much better quality and eliminate any background noise. I record my narration for the second time this evening and will put the new version on to my short film tomorrow. My teacher also suggested that I added in an extra title at the beginning of the film stating 'Matthew is my brother' as she did not feel that the fact he was my sibling was made clear enough at the beginning of the film.
