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!

Perhaps a large round table might mean a rug is not at all necessary. It could be a metal tray table, or carved wood like Rebecca Mitchell Interiors illustrates. Ideas also to consider, using multiple tables can be found at http://www.houzz.com/multiple-coffee-tables. I also agree with comments above that some color is needed on the walls. You could then hang round mirrors, or an unusual curved shape like RMI shows above.

16' long is a lot of room. Can you post a pic of the rest of the room? Remove every door you can. Every doorway does not need one and doing this one simple thing will remove a ton of bulk and make your space feel more open - no need to remove the hardware if you think you might want the doors back sometime in the future. Are you up for painting the walls and possibly the trim? Is this a sectional? If so, you might have to split it in order to get it to fit. The curtain into the bedroom is a good thing. I have used that idea, I love it, and I am not from India! Change them out for a lighter color and add panels to the ones you have - make them at least 3x fuller than the doorway. Pull them all over to the hinge side of the frame after the door has been removed. Your pictures need to be rehung and you can address that once you have found a furniture arrangement that works.

Hi Himani, What is visible from the pictures is that there are no walls that you have adjoining the sofa wall. So the best option to suit this space would be put a simple straight 3 seater sofa , very minimalistic & modern to go with your TV unit design. It should ideally be a low back sofa or a couch which can also be doubled up as a bed if you really need. To add to the space you can put a floor lamp next to the sofa or a corner table with a little tall looking table lamp. And a nice little rug in front of the sofa would be perfect.
