Your space has a little warmer tone than this, but you still can get the idea of placement of print/mirror, lighting and the decor.

I'd skip the sconces, you already have a lamp on the cabinet. One tall mirror or one large piece of art, a bit narrower than the cabinet and hung about 6 to 8 inches above it, will look finished. A round mirror would also bounce light into that corner. Keep the lamp on the left and the plant on the right so it stays balanced.

The pink flowers already look lovely against that dark cabinet. I'd pick artwork with a little of that colour, rather than matching everything to the wood. Try a paper template on the wall with the lamp still in place: if the shade hides too much of the picture, a shorter lamp may solve it without adding sconces.

Some inspro with wall art

You've got a pretty great size wall to work with and not really making the most of it with these random objects you've assembled. Step it up.
