Blender 2.6 - Internal render - Interior design

Hi! Well, i've been working on some interior projects on my own, most of them i'll include in interior tutorials that i'll start publishing soon, so i decided to share some tests of the images that i was experimenting on. I do planing to have more and more topics about blender internal render and it's capability of creating interors. Of course, i'll cover Cycles as well, and i have to say that even now, in early stages, i've done pretty heavy scene interiors, but for now, i do stuff with internal.

Images below are the node setups for the interiors.
