Initial storyboard

Because I am finding it difficult to create a story-line for my project, I've decided that I want to create an initial storyboard that will include props/settings that I would like to use. I will then use this to create a story-line around these things.

Things I need to include in my trailer

After looking at various other film trailers, I've realised that creating tension in this type of film is essential and in order to achieve this, the pace of the trailer has to start of slow, and speed up towards the end. This pace paired with increasingly paced/volume of sound creates the most effective atmosphere for any supernatural-horror trailer. Therefore I want to use creepier visual things towards the beginning, but pack all the excitement into the last 20 seconds. I am aiming for my trailer to last around 2 minutes.
