Finally, I create my scene as following:

For this scene the texture is not good enough, Because of some of them as not look in a dirty and old style,especially the pipe, actually i create some of rust for the pipes. But after the lighting, it looks not very clear and looks like no texture. This is a big problem.
Also the light is too dark for my scene. I need to do some more test in the following week.
