Some suggestions

Lower the TV and replace speaker with sound bar

Paint wall behind TV to match color of new drapes in Burnt Orange

Place round pedestal table in corner with new lamp

Move sofa over to center it on wall,

Select larger more colorful art work.

Add color coordinated toss pillows.

I suggest also that you lower TV and then remove all that stuff off the console. Get an area rug to bring in color and move your sofa and loveseat into the room a bit more onto the rug. Get a sofa table for behind it and then move art so it is centered over table and sofa. Lower the rd disks on the wall to eye level. Here are some area rugs. Once you get the rug then add a couple of pillow to sofas to tie in color.

Oops maybe can't have sofa table if sofa seats recline.

If keeping the 3 piece art center them over the large sofa & hang about 4 inches between each panel. Install draperies in color (perhaps blue or teal) from the ceiling down to the floor.
