Is it a silvery gray?

Yes the couch is kind of a silver gray

I think you have way too much furniture in the room. Remove the 2 chair and ottomans Take out the free standing bookcase. Can you do built ins next to the fireplace? I would add a coffee table (leather?) The 2 prints on either side of the firepalce should be moved and placed close to each other. Is there hardwood under the rug? if so add an area rug in front of the couch - with the silver gray sectional you can chose tons of colors - I like blues myself. Maybe add a rustic bench under the window for more seating, some wood would warm the room.

I can't do built-ins right now due to budget reasons although that is in our future plans. I am looking to replace the artwork on the sides of the fireplace so any ideas are appreciated. there is no hard wood under the carpet... house was built in 2012

That room was not designed for your couch pit. Most people sitting on it are not orientated to the TV as they should be. If you flipped it so the long was across the room from the fireplace would it block any entrance? I would remove both chairs and move the book case to one side of the fireplace perhaps get a matching of the other side. The art is too small to flank the fireplace.

if we moved the sectional it would block an entrance and it would cover some vents so unfortunately it needs to stay where it is.

any suggestions on art?
