Can you please share the room size and its future purpose?

Change the room color, currently all walls are with same shade, make only 1 or 2 highlight walls remaining walls to be with light shade and change fabric of the sofa if possible then modify the same sofa to slim it will increase the space of living room, also add some ceiling with hanging light once you do it your room will be luxurious.

First try to segregate all of your furniture and divided them among necessity and want. keep only that which is NECESSARY! if there is any space left then add a few from the list of want.

change the wall colour to something light to lift up the space and make it look wider. add smaller nd sleeker looking furniture. Keep it minimal. add some wall art an a nice rug. replace the coffee table to round ones. there are endless possibilities here. i can keep going and going.
