I would center that painting and add something on either side of it, possibly some wood carvings.

You know, I really like the a-symmetry of it. If you have other pictures that you want to display you could create a gallery wall, but otherwise I'd leave it there.

I'm liking the room as is but I would make the following tweaks: remove the white pillar candles and the iron work from the fireplace. See how the two pieces of art leaning against the wall now look on the FP ledges.

Move the black lamp to the left of the chair. Place a large tree/plant where the black lamp is now.

Get a smaller lamp than the one in the corner - it is overpowering, and put a table and reasonable sized lamp next to the chair.

Then move the coffee table to 18" or less from the sofa so it can be useful. I'd flatten the TV credenza against its wall; wall mount the TV on an articulated arm so it can be pulled out past the FP and adjusted for viewing. Align the big piece of art with the ceiling fixture and angle that chair to the left of it.

I like the scale and drama of the existing floor lamp! Works with everything else.

I like it too. I was going to suggest taking away the side table by the couch, moving the chair so it is under the left side of the painting, and moving the black lamp out to the right side of the chair. But I didn't want to be pushy lol

I love that asymmetrical look. I would raise the larger picture a little and then add the two paintings

that are propped against the wall under it.

I love your room! I wouldn't hang art that high ^^. I like the asymmetrical placement, but think if you center it over the chair, it will actually be asymmetrical on the wall, but balance with the chair and lamp. Or maybe first try scootching the chair and table a little closer to the couch so the right corner of the chair lines up with the right side of the art. Or if you like the chair exactly where it is, maybe instead of centering the art over the chair, line it up by moving the painting slightly to the right so the chair and right edge of the painting line up, like I suggested above.

Maybe I'm in the minority, but I don't like the asymmetrical look (I know, not helpful when it looked like there was a consensus brewing). But then, I'm someone with more art than I have room to display, so to me, the blank stretch of wall represents an opportunity.

I liked Wow's suggestion for laying out additional art.

I like the asymmetry. It gives impact to the painting and I wouldn't add anything else on that wall.. I would, however, slide the chair a few inches so that its arm (or back edge if you prefer) lines up with the painting edge (not centered under the painting). I might add a more substantial table next to it with a cool lamp on it.

Are you ever going to sit in that chair at night and read? If so, I would move the fab floor lamp closer to the chair, and if I needed to nudge the painting and chair over a bit, do that. If you like the bold colorful look and have someplace else for those other picture or want to get rid of them, then nothing more is needed. If not, why not hang them, the more art the better in my aesthetic but I am in the minority . . .

Move the sofa and chair away from the windows. Move the floor lamp and place a table lamp on the end table. Center the wall decor over the chair.

Try moving the chair so the right side aligns with the art. Add art as Wow Great Place suggested then hang the two pieces currently propped against the wall under the added art.
