This is a narrow path which leads into total darkness, the overgrown trees would frame the shot if we wanted a person running into it and also close in on the protagonist the further down the path they run. This would be difficult to illuminate in the darkness so we would need to film at dusk when it is light enough to see but not broad daylight. We could darken the film later in the editing process to make it more eerie. The leaves on the trees and the moss on the bare branches gives the whole frame an eerie green glow.
In my previous photo analysis' at the start of the project I mentioned how the colour or brightness of a light can change the mood of the shot. The same theory is applied here with the colour of the surroundings.
Most of the trailer trailer will be set in a house, there is nothing unusual about it. It is a regular home where the protagonist can feel safe and puts the audience in a false sense of security as she goes through her daily routine of coming back from work and picking up her mail. The disruption to the routine when she receives strange letters is something that could easily happen to anyone and makes this film more frightening than if it were happing somewhere or to someone unusual and this can sit in the mind of the audience throughout the film.
