You need an art on the wall with light colors to make the room brighter as the paint color is giving the room a dark look, the mirror is really nice but it's not helping to make the room brighter you can place it on the right wall above the other sofa but with a new arrangement you can place only 3 small mirrors instead of the whole set.
You can get a small table behind the main sofa and place some plants & accessories to give the room a luxurious lovely look.
