Ive played around with the images I have and have a mock up of the poster. This isn't final as I am not using images from the short film, or taken proper images for the poster. These are from my location scouting posts, but my short will include similar images that I will use. I have marked on rough placements of the different parts of the poster. I like the green colour palette and the two halves of the poster: the real world and the fantasy and I think this style lends itself to my short film.
Here are my current drawn flat plans for both my magazine and poster with two variants of each.
