I drew a very crude sketch, definitely not to scale, of how I see your room working. Essentially, you could treat it as two separate seating areas, which makes for easier and more intimate conversation when entertaining a lot of people. Trying to have everyone facing each other in a large room just won't work, and makes for very awkward conversation. I find that at parties and get-togethers, people go off in smaller groups of two to four, then mingle and move around the room to chat with different people. So, to that end, you could establish two conversation areas that will each seat six to eight people. You can also have some of your dining room chairs upholstered and comfortable enough to carry into the entertaining area to create extra seating here. In the far corner by the window, I placed a chair and ottoman, so that is seating for two, and before the get-together, you could place a couple of your dining room chairs over there to create a other small grouping for four. You should still have enough open area in this large space for some people to stand and move around, which a lot of people prefer to do at a party (I know I do!). The bright yellow sofa is a modern take on the old ?English sofa, which in think is the perfect foil to your ultra-modern sectional. The yellow is a bright, cheery - and unexpected - color, but works nicely with white and just says "fun" to me! The small blue tub chair(s) would be placed at an angle facing your white sectional, so you would establish a color,scheme of white, blue and yellow. To this, you could add black, Gray and darker blues through your accessories and artwork. The little blue ceramic drum stool adds a touch of the exotic (and more fun) and is easy to move around as a small side table to set drinks on.

we do in guest bedroom,, but not sure will go with colors I have picked out, and the great room is a vaulted ceiling ....I guess we will just have to see...our house is being built and will be very open..not alot of wall space.

Leather sofas can really dominate the room and can give an overall cold feeling. I would add some earthy elements, like a wood coffee table with glass or metal. Go to Restoration Hardware's website and look at their sofa room scenes. And I'm sorry I think the art is too harsh for the room. That's all your eye goes to in the room. too overpowering. I would look for something softer or maybe a cool mirror and I would add color to the room with pillows and some colorful lamps. I also think woven blinds would look great. They add warmth and give a finished look. The color of your window treatments should contrast your wall color a bit, not match it or else it starts to look generic and blah.. You have warm walls, warm floors and the woven blinds, like Hunter Douglas brand would pull it all together for you.
