When I see this picture I get a deep sense of depth. Makes me wanting to go there and see the place myself. Weren't you afraid to do all these photos inside that building? It's an old one, taking great pictures like these takes time and there are some risks... I guess being extra careful is a must... :)
Your just posting these now? wow... your wayyy behind! really cool shot, i like the muted greens and the nice smooth dynamic range at the end of the hallway.
