Brake disk diffuse-bump-reflect-glossyness

hi yall...

iv'e been searching for some nice brake rotor pics, but they are hard to find without any reflections, highlights and in a full-frontal view... so i made my own.

the examples shows a basic shape with only these maps applied in one arch&design material, reflection and lighting is a self-shot HDR environment.

size = 2425x2425
