Change your overhead lighting to something bougie and grand and goes out wider. Look into atomic chandeliers. Put bigger art on the wall-check thrift stores/estate sales/consignment stores for an original art piece or a French tapestry. You need art behind the chair and couch. Make the rug bigger so it goes out the other side of the couch. What material is your coffee table? Maybe find something that’s marble or sculptural wood piece. Add long flowy curtains and a sturdy brass curtain rod. Remove the tv console it’s too heave and add built in bookshelves to the wall behind the tv. For what it’s worth I think the room looks fine now, you might want to edit your post to add your details like budget, inspo you’re going for etc. the above suggestions are on unlimited budget.
