A few more pictures would help. But lower the TV (should only be an inch or two above the console and yours is a little high already), add some curtains, and declutter (or store items on the shelves behind doors or in baskets)

Pull out rug from under sofa - so feet of credenza are on it.

move tv down.

Sit TV on its console. Put blue chairs facing out instead of at each other. Put up curtains or drapes, pull rug out so console front legs are sitting on it. Then work on the bookcase (?) in the corner....either declutter it, or put it in another room and put a nice tall plant in that corner. A coffee table (glass/wrought iron) or ottoman would be comfy also. Also declutter your couch, chair and top of your console. I would like to see a lamp of some kind near the blue chairs but you are limited by the air conditioner....maybe move your tall amp over near the chairs, TV side and put a lamp/table on the end of your couch (as you are facing the couch...on the right end).. Will be a nice room.
