I was supposed to post today the final renders of my scene but that will be for another day.
It still doesn't look like i want it to look. Yesterday something i did to a material made the renderer shit on it's pants and in a fit of frustration i deleted all the materials and started to re do the shading from scractch.

The new ones look MORE OR LESS like i want them, but i'm still wrestling with the lighting and why the room looks so freaking dark
Made some experiments with the renders and GIMP and looks like a postprocessing step will be inevitable.
@hideki you mean it'll be done soon™ 
@karo When it's done™ 
It's VERY POSSIBLE that i'm asking blender to do something that should be done on post, but i want to get as closer as i can before using another software.
