Drafting and Planning (My Horror Trailer So Far)

For my A2 media project i am going to make a film trailer. I have chosen to make a horror trailer as i believe that it is one of the best genres for trailers as the fast paced editing and sound that can be used in the trailer.
Below is my shot for shot plan of my trailer so far  i think that my plot is big enough for me to be able to make a trailer of at least 2 minuets
Plot summary: Group of walkers get lost whilst walking in the woods and are cut down one by one by an unseen axe wielding man.
Shot Plan:
Establishing shot: The group walking along the path in the woods talking.
From the establishing shot fade into a medium close up of the group and a female member of the group realizing they have strayed from the path and are now lost.
Fade into a close up of a male member of the group saying that its getting too dark let’s stop for the night and look for the path when we have the light.
Quick fade to a long shot of the group around a small fire, cut to a medium shot of a member of the group looking into the flame :shot holds for around 5 seconds: (no sound other than the fire flickering for 5 seconds and then branches are heard breaking)
Quick cut to one of the male members walking towards the noise to investigate whilst yelling "everyone stay by the fire.
