I’d make the tv stand and the other piece straight.
And then add a bench on either side of the fireplace, not against the wall…

I was wondering about the angled pieces too but have to see the rest of the room to understand if there's a space reason for that layout. Based on the bit you show us, I'd place a large floor pot / vase something in front of right outlet. On left side I'd use white electric cord tubing to corral the cords & run the tubing along top of radiator. Run the cords strIght down from outlet to about radiator height then through tubing. I think the cord clutter doesn't need hiding just tidying.
