I have a few comments about this space that I feel will help to create a cohesive whole and give you the look that you are aiming for.
Artwork on the back wall behind the sofa should be a priority as well as window treatment for the two (or more) windows in this space. Consider a large framed poster, whether a colorful retro advertisement (try art.com) or a photograph mounted on aluminum (try Lumas Gallery http://www.lumas.com) or even saatchi art ( http://www.saatchiart.com). Aim large, maybe as big as 60" x 30".
Window treatment is important because, even with a view, the windows are cold, black rectangles at night. A simple roman blind with horizontal bones will work well. Here's the tricky part: I suggest adding artwork between the windows that will tie the wall, windows and additional artwork together with your furniture and accessories.

I would say no to the wall of mirrors. I

the furniture shown is not mine...as mentioned the pic is of the time when the place was up for sale. my furniture is brown sectional in place of the grey sofa. Will post a pic as soon as the unnecessary clutter is rid. Just moved two days ago. Do not have a rug, but have a large entertainment center with fire place on the opposite end kept diagonally in a corner. Plus a high dining table.

Once you post pictures of the furniture and other elements you are putting in your room, it will be easier to make more accurate suggestions for your gorgeous living space. Thx!
