Some dirt here and there was added, some material wearing down, and some additional work on the shaders. This extra texture work was not made manually, i mean, i didn't spent the night drawing by hand all the dirt, all the material wear and scratches. I hate wacoms, yeah... i know, i know, i must be crazy right?. Instead, i used a sort of procedural way, with the help of the occlusion and cavity maps, i mixed some dirt and scratches textures and voilà!, the job was done... yeah i wish it was as easy as it sounds...
Here there is a render still:
And Here there is a turn around video:
