WE need to see the whole for the style. I would not use that piece I would get a nice piece of art.

Take a picture from further back and also pictures of the entire room.

All these items are from Kirklands.

Add Framed Art or Sconces

Framed botanical prints, vintage sketches, or minimalist abstract art on either side would create symmetry.

Alternatively, wall sconces with candles or lantern-style lights could flank the piece, enhancing its charm and giving off a cozy glow.

Consider placing a shiplap panel or board-and-batten backdrop behind the wall piece to give it visual weight.
A thin wood frame around the iron piece itself can help anchor it, especially if the wall is large.

Some idea:

a larger horizontal framed piece would be suitable for your sofa.

your wrought iron piece may be more suitable above a table with other treasured items.

perhaps in an entry way? or more confined area?
