I have digitally created an idea about how the final banner may look. As this is a sample, the final image is likely to be longer and feature trees in varying densities.
Above are 2 variations on how the imagery may look. I have included some potential textures and tree positioning and included the idea of children trying to find red riding hood amongst the trees. In future versions I may also include other things for them to find for instance the wolf, other animals and perhaps fruits of different colours.
