This is an example of environment concept art for a game. This is concept art for Batman : Arkham Asylum. I really like the look of this concept art because it places you in the perspective of the enemies rather than Batman.
Batman Art - "Because he's the hero that Gotham deserves, but not the one it needs right now. and so we'll hunt him. because he can take it. because he's not a hero. he's a silent guardian, a watchful protector. a Dark Knight.
