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.
Gotham has its fair share of memorable characters, but one of the best so far is future villain Edward Nygma. And all of the riddles Nygma has made on Gotham so far just add to the charm of the character.
