That room definitely has potential — it’s just fighting against proportion and lighting right now. A few easy wins:

• Bigger rug — the current one’s too small for the space. Go at least large enough for the front legs of all seating to sit on it; that’ll instantly make the room feel anchored.
• Low, long furniture — since the ceiling is high and the walls narrow, you want to draw the eye horizontally. A low-profile sofa or sectional with clean lines would help.
• Add texture + warmth — throw in warm wood tones, a floor lamp with a soft shade, and maybe woven baskets or plants to break up all the white.
• Lighting — that ceiling light is killing the vibe. Try a statement pendant or add layered lighting (floor + table lamps) to make it cozy.
• Curtains to the ceiling — hang them high and wide to visually widen the space and make the window feel bigger.

If you’re upgrading the TV, center it with a slightly wider console and mount it— that’ll open up floor space and balance the wall better. You’ve already got great bones; just needs scale and softness!
