Thriller opening scene - insert editing idea

We have filmed inserts of different aspects of the building that we thought were interesting and could create a creepy depiction of the location to intensify the opening scene. I think that the film Fight Club uses inserts very well as they have them throughout the film and they flick on and off the screen, however these inserts flash up a bit too quickly so sometimes you cannot see them so I think that we will use it like they do however they will last a lot longer on the screen. I want this change what Fight Club do with theirs as I feel that the tension will be better if they last longer as the audience can properly digest what the location is like.
