I think the yellow and grey might bring out the gold-ish-ness of the couch.. I'd try to go with more blue colors.. Maybe some navy pillows and a rug with the blue in it as well. The curtains, that ying-yang rug, and the lilac rug just gotta go.. They're dwarfing all the sophistication this room will be able to have with that tile floor and those big beautiful windows. I love the dining room chairs!

There is a specialty lighting store near me that I am going to soon with photos to work on lighting at my house. I will show them your photo and see if they have an idea. Probably won't be till Fri or Sat but will get back to you.

I think you need to ask yourself some more questions. If you have children - get something that can be cleaned easily. If you have pets that get on the couch - again, get something that can be cleaned easily. Do you want a sofa that can convert into a bed? How humid is your climate - think of the upholstery and possible mold/mildew if the sofa is not in a location where there is good airflow. If you live in a dusty climate, find one that can be wiped or vacuumed easily. MY first consideration is if the couch is comfortable to sit on!

Ok there is a lot that you can do to decorate this place. You can put nice white/cream curtains along with white/cream curtains so that you can use net curtains one when you want more light. You can place a small decorative plant on that window. Another thing is that you can do is cover the wash-basin pipe. You can use a couple of small frames to hang on the wall that compliments the color of the wall. Talk to top interior designers such as Tasko.
