Environment Thumbnails

Using the silhouettes, I complied a number of thumbnails for possible concept pieces.
I particularily like the top row; 3rd and 4th ones, 2nd row; 3rd one and all of the bottom row.

I feel the bottom row and row 1, 3rd thumbnail illustrate the environment the most with the mix of a lot of foliage in weird places and the amount of damage to the buildings, cars and what not.
