Well, the idea I came up with after a ton of brainstorming, is the idea of a city in the trees, built by kids. Think tons of tree houses all linked together by ropes and buckets and bridges. The "end game" is the sky in the background. Looking past the city, through the trees, you can see an impending doom about to befall these dendri-domiciles. Huge clouds of fire are moving towards the city. Think the movie Independence Day style clouds as the alien ships were first appearing over the cities.
Anyway, the colors will be very drab and muted in the foreground which will contrast the sky burning with rich browns, reds and oranges.
Highly stylized trees reminiscent of Tim Burton Movies will fill the landscape. The house them selves also look like something straight out of beetlejuice. I'm honestly tired of seeing the post apocolyptic scenes that are filled with litter everywhere and gritty and dirty. I'm moving towards a little different style.
The idea is to place various objects around the treehouses that are important to children. Teddy bears, books, slingshots, etc. I want to make it clear that this is a play place for children. I believe that adds to the pathos of the piece, given the player more of a reason to stop this impending doom.
My concepting skills are not the best... but below are a few sketches and thumbnails I did.
