Not everything in this scene is cel-shaded, because I did not have time to go through every bit, however, I think it still looks good. Also, even though the wall in the background looks to not be cel-shaded, it actually is. Its just that the map is so photorealistic that the cel-shading does not stop it from looking super photorealistic.
