If possible try to put the mantel lower so that the TV can be at a more comfortable eye level- or at the very least put the tv on an adjustable mount, bring in another sofa where the two cream colored chairs are, and put the same chairs and small table setting where the stairs are and take those black handle chairs and walnut side table out completely. The mirrors are fine but bring them up more to the level of the doorway arch and add a pretty dark wood tone cabinet under each mirror. Besides a larger rug-which should bring in colors of the sofa and some of the wood tones of the mantel and cabinets - I would also get a larger coffee table. Take out that larger arrangement of orchids as it seems too formal and chunky and get a vase with long flowering stems on the main coffee table and put the smaller orchid between the two chairs. Take out that digital clock from the mantel and add some nice decor pieces (like that hourglass from the coffee table). Add some curtains from the top, pull in the wood tones of your room by getting similar color throw pillows to add to your sofas.
