I would move the couch away from the wall, further into the room and centered on the TV. You would have to ignore the fireplace as a focal point and put a love seat in front of it and a chair on the other side of the couch, in far enough so that it won't totally block the opening. You could also put a chair in front of each window and another chair perpendicular to the couch on the other side. It's not a large room and I would try to use furniture that is not too bulky but still large enough for comfort. A glass and metal coffee table will give visual lightness and open up the space since you'll have quite a few solid objects for the seating. I'm not sure that industrial accents will marry well with the dark wooden, rather traditional TV console. You will need some side tables to hold lamps, etc. and perhaps have a floor lamp somewhere. An area rug incorporating the beautiful color of the accent wall and pillows incorporating that color would pull the whole look together.

you're painting all of those walls earth brown?? why? it's going to look like a cave. I'd paint out the trim to white. all of the baseboards, door trim and window trim. will look nice and fresh in white, especially if you want brown walls. (i'd really rethink that color). any rugs? They need a large area rug in front of the sofa. What about artwork? any pics? (not photos)

In my opinion you could go neutral sofa, neutral lounge chair, and green or patterned accent chairs. Would you want a pattern on your accent chairs? Or would you like to keep pattern to the rug and curtains and accessories? Another thing to think about is armrests versus no armrests...I think no armrest would look cleaner for the accent chairs, but I don’t think they would be super comfortable. Here are some options

The sectional looks better than others. I advise you to make it like this. Moreover, for your room, you can take vintage furniture. It will make your room richer. When I moved to my new house a year ago, I noticed that something was not reaching the living room. After a time, I decided to change the furniture and I opted for a vintage one. After changes, the living room looks better, more colorful and this type of furniture gives unusual magic to the room. If you want to find more about vintage, look on osvaldoantiguidades, from there we bought our furniture.
