Thanks for the feedback,
Kroyo I was worried about that since I was forced to use that texture on the desk, I tried give a bit of brown color without mess with the scene, looks like I have could make it darker right? ;D
Slashed you're welcome, and yes, there is already a few weeks that I'm looking for a way to generate normal maps, and I'm aiming at the CrazyBump program, I'll try get it soon as possible for a extra detail on everything.
Indeed, they were most simple as possible, my modelling isn't that great yet, and I don't have much time to study and try my own complex stuffs but I'm trying get done a complex sofa using only 3DS Max in my free time.
Yeah, I didn't tried too much the lighting of the computer because I hate when I have to use VrayMaterialLight, it's really annoying the artefacts that you may get using it wrong haha.
