just a quick model of a very simple bathroom, i am a beginner, so keep that in mind
i watched one of Andrew Prices tutorials to learn about cycles texturing, heres a link http://www.blenderguru.com/videos/rendering-an-interior-scene-with-cycles he has other tutorials, i strongly recommend watching them, they are very helpful.
Like for me it looks nice, do u have any good author of tutorial which relates to use of nodes?
