Still on my nostalgic gaming kick, and I thought maybe one of the Levels Lara goes threw is in the Subway. Where shes in the subway cars fighting bad guys and this BG layer is passing by in the Back ground. The stage would be made up of 3 layers for the BG, this one of the tunnel walls, a second layer that is of a train passing in the opposite direction and the train Lara and the bad guys are in. I will try and draw those layers later, and maybe try and animate them
