'Avenue' Voice over and character links

We decided that for our soap trailer we were not going to just have a music track alone, that we are also going to include voice-overs in certain areas, although we are not totally sure on this here are our ideas nevertheless. I tried to picture where each character would meet in the trailer as my inspiration is a chain of stories with certain characters bumping into each other and then seeing where every characters storyline goes from there. These character meetings are liable to change however and so is our voice-over script. We felt like we couldn't solely rely on 'action' and 'expression' alone and that there had to be some dialect. We came up with potential voice overs which would be thoughts or small bits of dialogue throughout the trailer to show the audience more of our characters' personality and the relationships among them.
