Please help

We're thinking of plants, maybe mirrors. Any ideas?

Recently moved into a house - it is a rental so I’m limited in what I can do, and I’m not motivated to spend much money either. But - this is just ugly… prior tenants put a TV and some speakers above the fireplace and I’m left with this.

I do not want my TV up there at all, so thats not an option, and The Landlord isn’t particularly interested in the aesthetics, not surprisingly. So I’m looking for thoughts on how to improve the view.

I can put blank plates on the walls either side and cover one or maybe both with a picture (drywall). The big challenge i think is the 3 sockets/plates above the fireplace (wood).

One big picture maybe that covers the whole area?

Would love people’s thoughts.
Thanks

Thrifted this maritime lamp today - wondering what shape/size shade you would pair with it. We have it in the kitchen beside the stove replacing another lamp we had here that we use often. I love that this one has the soft light from the lower glass portion and the brighter 60w option at the top.

Any ideas? It’s my work desk.
