Who would be the audience for your opening sequence?

By creating a questionnaire and looking back at it I know that my target audience are mainly females aged 16-18. I also know that my audience is people that go to the cinema often and have horror as their favourite genre. Also I found out that my audience will be watching the short film for the story line, not the special effects. Therefore I need to make my short film with straight cuts and not too many special effects so the audience feel like it hasn't met there wants and needs.
