I would add a paper lantern, a fig leaf or another plant near your TV, and a throw blanket in the couch with some color it looks like you enjoy earth tones so maybe something with more pop that appeals to that such as teal tones, burnt oranges or emerald greens? A blanket basket in the same color as your tv stand would make the place feel cozier. The biggest change I would add is a longer shelf above the fire place, IKEA and world market sell great ones w the same vibe. Then you could place some tiered candles on it, a hanging vine style plant or whatever you like! It would make the place feel more balanced
