Move the art from the wall behind the chairs (it's not really needed there - there's a passage there) to the wall above the sofa. Considering the size of the art (it is too small), hang it not in the center, but on the left and add, for example, a pair of small frameless mirrors with non-standard smooth contours (but not a circle or an oval). Or instead of mirrors, 2 small light pieces of art. If you take a photo of the sofa without perspective distortion (straight), I will sketch out the location for you in Photoshop. Just try to fit as much space as possible on the sides of the sofa in the photo. It will also be helpful to get a photo of the entire room.

I also want to move the sofa, along with the tree and the table, a little to the right - it is too pressed against the window.

I think you need one large piece above the sofa and the art on the opposite wall looks as if it could be perfect there. I would look for something like a tryptic or 3 related pieces to hang where the current large piece is. Since it's a bit like a hallway there, something you can pass by as a grouping would be perfect. I don't think you want two large pieces in both the spaces.

Something like this: maybe not this big, tho

Thank you for the feedback! I wasn’t sure if 2 large pieces of artwork would balance a room but these are great examples!

Perhaps consider an item that is more three dimensional.

I love the 3D accent idea! Where do you recommend purchasing something like this?

I’d first address the other side, as the art feels lost (is also a bit high) and the wall needs grounding,

Whatever you add above couch, I’d avoid adding just one piece and proportions are so important. Be sure to add cushions to tie in your rug and the art (adding a bit more color would be nice).

Awesome! Thank you!

You room looks wonderful. The only thing it feels like it might need is texture. You can add texture with textured pillows, textured artwork, textured rugs, etc. Below are some ideas on what type of artwork could work in your space. You could do a gallery wall, a textured piece of artwork over the sofa, or just one large painting that goes with the colors already in the room. Visual ideas are included below.

It looks like you could easily do an art piece with silver, grey, white, gold, and black. You could also add pops of color in the artwork and add more pops of color via textured colorful pillows. You could do a triptych, 2 medium pieces, a gallery wall, or one large piece. Please see some images with art ideas below.
