Electrical distribution panel - Material definiton & Asset Presentation

I´ve created a new hand-painted diffuse- and specular map, to make the metal material looking more believeable. Also updated the lighting to see how my textures will react to light generally, and also to improve the quality of my pictures because of reflections and shadows.

I was concentrated on the metal only, other materials will follow. The normal map is nearly the same I´ve used in my last post, so I didnt show it again.
