You have all the reasons to redo the house, its very lifeless and looks worn out. I feel creating a separation will terminate the spaciousness of the room. Adding colours will surely help, Since you have a tan color sofa,I suggest grey, white or light blue color on one of the walls. Add some art works of the color you chose for the wall. This room needs some fillers like , books, throws, candle stands tall and lean. YES DON FORGET 1. Mount the tv on the wall make some space on the floor and Fix a large size mirror ( Wooden Frame if you can afford).

The first thing that bothered me in this room is the distance between the seating area and the tv area and that both seem unrelated in everything. I think what you should do to pull everything together is the following: 1) Move that sectional away from the back wall and the curtains (placing couches against the wall is outdated now) and closer to the tv 2) Center the coffee table under the chandelier with the sectional placed 16 inches away from it 3) get a console table of a height equal to the sectional's back 4) place few decorative items, stacks of books, candles, lamp shades whatever you find suitable on the console 5) someone mentioned that the two accent chairs are not in scale with the room. I totally agree with that. You need wider chairs with a low back 6) A rug is a must and two are better than one, layered of course !! But make sure the biggest one is big enough to place all the seating on it. 7) pillows and a throw will add warmth and texture too...
