You could make your room a reading retreat by adding a console (with tv above) and store books, magazines, and photo albums, etc. Try pulling your rug out as well Suggest replacing the small table between chairs with something larger to make that area feel more substantial; but more importantly, for the addition of a good reading lamp, book, coffee cup, etc. Add pillow and a throw and for more comfort, you could move the chairs back a bit as there seems to be room and add ottomans.

Can you turn the pics so we can see them and also the size of the wall would be nice.

No one has answered, so I will. you need a big piece of art. And, I know you didnt ask, but you I willoffer you a bonus tip, and you are free to ignore it of course. You can consider getting rid of the giant entertainment center. You most likely have a flat screen TV that will look nicer, more sleek, and offer better viewing simply hanging on the wall, with a narrower console underneath. The media center is so dark, and towers over the room. Without it, your room can feel lighter and more spacious.

It's a lovely room with lots of potential. I would paint the TV wall in a calm, deep accent color. Like a subtle taupe gray to compliment the fireplace and the couch. Add a long console table under the tv in a warm wood tone. (Tall enough to hide wires and give a focal point and wide enough to add thin accent lamps or tall candle sticks or vases.) Move the plant to the left corner. Center the wine rack on its current wall on the section away from the cut out. Find a unique mirror to hang over the wine rack to add depth to the room. (Like a window would.) Find matching pieces of large artwork and hang on either side of the TV - spaced just a few inches past the corners of the large console.. You can place the lamp to the left of the wine rack for added light in that space. A warm wood tone mantle will also add warmth to your room. Good luck! I hope you show us what you did when you're done!
