Wow, your space looks spotless!

I too really like the space already, I do like the recommendations given about the wall hangings also and I think a nice tray on the coffee table for a candy dish and floral arrangement and a couple of books or magazines and coasters that would be nice and if your able to fit a larger plant in the corner next to the window and center the collage over the console table.

Don't know how big you want to go....but agree with others about the mirror and sconces. A nice piece of art over the couch would look great. Replace the tv stand with something less "techy" looking and more in keeping with your furniture. Do you need two full-size couches? Maybe do two recliners where the current striped couch is. I like your tables. Agree with Mon, place a nice tray on it with a nice (real) plant. You did a good job making sure your curtains are full enough, but the window would look much better with a the panels on a single rod. I realize you want to keep as much of the window open as possible, but the current configuration isn't good; it looks as if the poles extend pretty far beyond the window trim. You might be able to join the two (they make double-ended screws) and put a support bracket in the middle. You can get hold backs to keep them off of the windows. You do have a very nice room, just needs a little tweeking.

I agree that you need new curtain rods that go all the way across even if you never close the curtains. Make them very simple, perhaps a bronze metal. In addition to the above suggestions of removing the mirror and wall sconces I would remove a lot of the small pieces that are scattered around, also the vase with the flowers that look very fake. You can find faux flowers that look more genuine. These I would put in a simple glass or porcelain vase that doesn't interfere with the beauty of the flowers, which should be colorful. I would find more stylish and clean-looking lamps. Family photos are okay discreetly displayed on a table, but I would remove that cluster on the wall and find an interesting painting to put there. More colorful pillows would liven up your scheme. Since you have wooden side tables I would choose a metal and glass coffee table for contrast.

How many do you need to seat on a regular basis? What has to stay besides the coffee and end tables? What is your budget for changes?

We agree with removing the mirror and sconces and hanging a piece of art. We also think you could add a pop of color to the space. Perhaps when you add the art above the sofa it will add some color for you? Right now it looks like you have the right amount of seating: two sofas and the recliner. So we don't think you need different seating options, but here are some ideas if you want to update your space:

Agree ditch the mirror and sconces, add a honey tan leather recliner sleek and modern, add new cocktail table and end tables.....in wood and stone and metal. Modern art over sofa 2/3 width of sofa with bottom of art 5-12 inches above the back of the sofa....new throw pillows in suede and leather and linen in colors of striped sofa only deeper colors. One inch ORB curtain rod in 1 inch diameter minimum.....needs to be heavier. Love the swirly lampshade lamp; does it have a mate. When that is all done maybe an area rug under the cocktail table.

Here are some ideas but there are 100's of tables on Houzz where I found all of these!
