You have a beautiful piece of art above the fireplace. Take colors from that for couch pillows, etc. I would also get a coffee table and have it close enough to the couch, so that it can be used when sitting on the couch, and not so far out on the floor. Some end tables and some lamps would look very nice too. Right now, its all pretty much one color or shades of color. I like the blue chair. I see a similar blue in the art work. I would, however move the artwork down a couple of inches. Its up too high.
