Hi, it's difficult to provide suggestions without seeing the color and style of your living room. Are you looking for traditional or contemporary feel?

There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

I'd go with either another neutral (gray, cream, etc) or a rustic look that wouldn't compete with the floor but would harmonize with it... (You don't show your TV, but be sure to get something significantly wider, for balance, if possible.)

There is so much you can do with the rug. You can go with a modern feel by bringing in metals, glass and creams with pops of orange or greens. You can go mid century modern by emphasizing the orange or even traditional with woods and beiges with hints of colors. If this was my starting point for a room that just needs to be cozy and comfortable, I would do a statement bed with darker wood. I would keep the curtains very light, and also the bedding. As there is creams in the carpet, I would steer clear of white, but use off white / beige for the bedding and curtains. Then I would use the orange and greens as accents in the room. Good luck and enjoy the process.
