I'd say the lighting needs a bit of work. Get rid of the tv and the images of the wall, just while your working on the basic light setup this will make the room a bit easier to visualize I think. I'd also say the floor and the cabinets the TV is standing on are to glossy.
Try using one lamp and getting the light to falloff so one half of the room is lighter than the other.
Post up some shots when you've tweaked the lighting. I'll try and offer a few more suggestions tomorrow, right now i'm off to sleep
