First I needed some authentic looking childs artwork, you'll need an 8 year old daughter for this and I happened to have one handy :)
I did feel a bit guilty asking for pictures of ghosts and such but actually she loved it and didn't mind at all.
This is the original drawing for Scene 3; The parlour scene.
Each picture for the movie was transfered to the computer and into photoshop.
I cut out the pictures into separate elements and added an alpha channel to each.
Each element was mapped onto simple geometry in the scene and lit. Animated elements were linked to dummy helpers and the camera moves timed to the music track; London After Midnights 'Demon'
