Are the sofas covered to protect from pets? I would move one sofa to face the tv, bringing left arm close to right arm of perpendicular sofa. A table with lamp could complete that corner where the arms are close. One of the chairs placed where the sofa you moved was located, and a narrow “C” table for drinks, etc. The second chair to a bedroom, maybe? The “cart to the left of the fireplace is out of place, so remove. A rug to anchor the furniture and a round coffee table. You may want to add a nice bench or hassock (moveable) to the right of the fireplace for additional seating. This should give you space to move in/out of room. The chandelier would look great over a dining table. Other ceiling lighting will depend on what you need. Have fun.

I was about to type the same thing.

Put one of the sofas facing the TV and get a round coffee table. I would look for one that has dark metal legs/base to more like your chandelier, or get a round upholstered ottoman. Move one or two of the chairs in front of the windows.

Personally I would paint the room a color with some pink in it, very much like your chairs.

Two etageres to either side of the TV might be nice. It would be nice to find a shape like this is silver or black or bronze rather than gold (and i'm not suggesting this pink for your walls)

I would get the biggest artwork that you like and can afford for behind the sofa.

What do you think of this for behind your sofa? It's huge -- 61 inches wide and 49 high.

If I had that painting on the wall I wouldn't bother to paint the room pink-ish like I said. This would do the trick.

I would remove the cart thingy and get a wider console for under the TV with room to display your cool flower arrangement, etc. Your mirror needs some company on that wall, but finding art you love takes time and patience. Just keep looking.

It's a little bland and boring. The furniture is lovely, but you need to inject some color and pattern. Get a rug with some blues and greens and find some throw pillows for the sofas that will work with the new rug.

Something like these, perhaps:
