pyroluna: thanks for the compliment, and dropping by once again. the renderer i used, vray for sketchup. never mind the graininess, it keeps up with the quite dirty atmosphere of the room.
lapx: thanks bro!! my technique for the carpet, import any colorful jpeg or bitmap into sketchup and use as texture. after that put some displacement on the texture with a multiplier of, say 5 to 8. that's it!! you have a colorful carpet in your scene.
