How should i furnish my living room?

i live in a 1bdrm apartment. the living room isn't very big, but it isn't tiny either. there is a big window/sliding door out to the balcone. i have a HUGE tv that's on my floor (inherited from my parents) and i have it sort of in the one corner, angled, so it's not right against the wall. it has to stay there because all the outlets and cables are in that corner. there's nothing else against this wall. against the opposite wall i have a loveseat and 2 end tables to each side, and a coffee table in front of the loveseat. in the opposite corner from the tv, i have a la-z-boy recliner. the one side of the room looks really nice, but the other wall is totally empty. i was thinking of being like a big shelving unit to fill up the wall, butall the big ones are super expensive, and one single cabinet, or cabinet and hutch would look awkward. what do you think?
