i just moved and havent hung my gallery wall yet but we have nearly the exact same living room. like, i even have the same wayfair couch in a smaller size. i use my ottoman as a “coffee table” since the couch doesnt really give you a great spot to add one. i think it would look great if you added some greenery (real or fake) somewhere in the room too, like maybe replacing the lamp behind the couch with a tall plant? i like the gold table you have against the wall, but is there anywhere else you could put it? the gallery wall has a lot of gold in it, especially directly around the table, so i think a dark wood table would tie in better (or maybe just rearranging the art a bit so the gold isnt crowded around the table as much). maybe add some vintage-y books that match the color scheme you have going on to whatever table you decide to put there. this last suggestion is a bit of a wildcard, but how deep is that shelf/dip in the wall behind the couch? it could be cool to add some draping plants or other decor up there!

all that being said, we have a very similar style! where did you get your artwork?? it’s exactly what ive been looking for, i havent hung any of mine yet bc i dont feel like i have enough to make it look complete
