Audience Feedback from sample scene

I've got some feedback from our sample scene of our film with the working title 'Roadside'. The main feedback that was given was that we need to provide more anchorage for the audience that the boy and girl had just had sex. From this advice, we have decided to shoot more of the house and include more content in and around the house to create the feeling that the killer is outside watching them. This will also allow us to set the scene and provide an establishing shot at the beginning and at a structure to our film.
