Looks like it might fit better if you orient the rug horizontally.

Why isn't TV on wall right of fireplace, sofa perpendicular to that window?

Are both your seating and TV unit on angles in the room? Maybe there is a better layout for all your furnishings. That layout is pretty unique and not conducive to art on the walls.

Slightly off might appear to be a mistake. Furnishings at a 45 degree angle sometimes will work in the room is large enough.

Thanks for your feedback. I prefer Couch horizontal but we've tried several things and looks better to have TV caddy corner since it wouldn't work in front of window next to fireplace. I didn't attach a picture where the large Slider is to the left of the TV. Thanks for the info on the wall art. I never thought of that.

Thanks for all of your feedback. For some reason I don't see where I can reply to the other comments so I'm replying here. I don't have the TV or Couch to the left of where the TV is now because there are big sliders to the back yard there. I tried it but I don't like the couch in front of the sliders. I appreciate and will consider all feedback!
