Accent walls are usually wall with windows, doors, FP etc. I think it would be better to move the TV to the left of the FP, put art over the FP and have the 2 floral chairs face the window

I would not paint that wall. I would paint the fireplace surround. I think a dark charcoal would look great.

Do you want help with the decor on that wall?

Decor help would be great.

Okay.....here goes

-the white furniture looks nice but the floral furniture looks crowded there. I'd choose the floral or the white chair against the window wall.

there are 3 pieces on the wall to right of fireplace that look odd.

Are those stanchions? Why are they there?

I see bookcases on either side of the fireplace

tv cord should be hidden in the drywall.

Can't see much else, but I'd start with the furniture.

Any suggestions for a dark charcoal color for fireplace surround?

If you are keeping that coffee table, I'd choose a color similar to that.
