There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

I like the ceiling. I think the hanging lights are too fancy and distract from the ceiling decor. A simpler light would look better or sticking with the canned lights you have. The walls have too many big, black things on them. It's hard to tell if they are windows with shade --- in which case I'd pick something lighter, perhaps to echo the ceiling, TVs (how many do you need?) or what. I'd consider a big piece of statement art in the place of at least one. If you're on a budget, get a large, high quality photo in the right colors, you can take it yourself. Sepia and black architectural might work. I like more color and more natural light. You may have closed the shades for a better picture, so it's hard to comment on the light, plus windows are a feature of your room, not exactly a decorator's choice. I would consider how to get a few small pops of color in, pillows, flowers, candles, maybe even a runner rug along the right wall. If you are doing this as part of a portfolio, the entire ensemble would look more welcoming with a few touches like someone lives there. Something on the coffee table, for example. A few books and a candle. A tray with tea things, a vase of flowers or basket of fruit. Pick one or two things and make it composed. You see this a lot in designer Houzz photos. Here's an example, you note this picture would be a lot more stark with an empty table: https://www.houzz.com/photos/21-house-contemporary-living-room-san-francisco-phvw-vp~60642

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.

First of all, I don't think that furniture is comfortable enough to sit and watch TV, so the TV should be remove from that room, the purple wall paper and the purple furniture is too much, you should consider another color for that wall and the furniture against the wall it doesn't look good. What is that room at the end is kind of dark and I cannot appreciate exactly what is the purpose of that room. I'm a firm believer in skylights, we have skylights in the laundry room, kitchen, living room and office, they make a big difference. (if you cannot have skylights (or tube lights) can lights are a great option. There are a lot of great ideas from everyone. I can't wait to see the after photos.
