Can't comment on feature wall but this space has so much potential. Rip out that dated ceiling fan and put something modern and spare in its place. Invest in a new streamlined fireplace insert and ditch that vintage ugly one. You'll be glad you did as you efficiency will be much improved. Although I usually prefer to keep original features the cedar T&G above the fireplace is a mismatch with your stunning wood floors. It would look much improved with painted to match drywall. Is this your furniture? Wait a minute... Is that a smoked mirror glass wall I see!!

Thank you..nope this was from the listing we bought this place a year ago and are planning on some renovation, I will upload some recent pics shortly

And do remove the chair rail to move the room forward a decade or 3 for a more contemporary vibe. This style suits traditional homes but doesn't work here.

nope its not my furniture, we have a brown sectional in there, I have attached photos on how I want to renovate, but to start with I want to change the fireplace and I was wondering if hanging a nice painting up there would look nice, or doing something similar to the picture below.
