First up is an image of a slide taken in Chernobyl which is situated outside a school.
I feel that my playground scene should shall be covered in snow and set in a night time environment. I feel that this would produce the eerie feeling I'm trying to recreate. This is because with the snow it creates a orangey unnatural colour which I feel would add to the overall eeriness of the image.

I also recommend looking at the other photos of Chernobyl tour as they are rather haunting -
