– I feel like the lamp doesn’t really fit in the space.
– I would maybe add some decorative objects/books to the lower shelf above the fireplace, move the tissue box off.
– I would think about replacing the three pictures above the tv with something else. The scale seems off, I would add something larger.
– Overall the living room seems a little dark / cramped. I would look for a coffee table that maybe is glass or smaller in scale to open up the room a bit.
– I would replace the bookcase next to the tv with one that is taller and shallower. Then you’ll have some more room to put whatever is in front of the fireplace into the bookcase.
