Concept artist, Carlos D’Anda just released the artwork for the Batman game, Arkham Asylum. He posted the awesome images on Deviant Art. I always like the concept art more than the final product. For me, there’s no limit with the sketches. The artist can just portray the subject as he sees it. Then it moves to other area of development where sometimes the concept isn’t captured anymore. I think overall, Rocksteady succesfully translated D’Anda’s style of exaggerated and dynamic art.
