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.

I'd suggest dark red curtains if you need curtains at all -- the windows are beautiful as they are, and I'm not sure whether some kind of blind might not give you the ability to darken the room when you want to. On the wall, if you are real fans of any movies or TV shows, three big posters would be fun. Otherwise, I would still suggest using three pieces of art there of that size, all equal in size and somehow relating to each other. Three floral works, or three works in the same style, perhaps. I think a large plain textured rug in a light neutral from one of the cushion fabrics would tie the space together well. You might also consider a lovely low coffee table on the rug to lay out your snacks and drinks for serious media nights.

Abhishek, Not sure what you are referring to as mirror like finish here. Please highlight or mark it. Walls seems to be treated with wall papers here. Thanks Nitin Cornerstone Designs, Bangalore.

Hey Kriti, The wardrobes are white so any color/shade will match with it. so you can go for louvers paneling, add a mirror, carved limestone or you can go for cheaper option by adding beading with cnc corner to give a european kind of look. You can check that out in our projects for reference. Even a tropical or any other themed wallpaper might look nice based on the aesthetics of the room.
