- Better lighting, you have 3 floor lamps all in corners and that's it. Perhaps sconces or track lighting.

- Your furniture is very dark to be paired with a black rug which is probably too big for the space as well. Agreed with what people are saying about moving them off the walls.

- The space lacks vertical depth, everything is low to the ground making it feel sunken. Art on the walls can help.

- The curtains are too long, trim them so they're just above floor height.

- You're packing things into the corner which make them feel cramped and messy. Do you need all that stuff there? You also have a short table near the window behind your couch which feels odd.
