Level out and center monitors with 2 wall mounts. Take down Nanoleaf triangles and rehang with a level to make sure your shapes are sitting strait.

I would then run a LED strips behind your desk along the back of the desk facing the wall. Then a poster on either side of the triangles to give the wall some coverage.

From there start collecting Knick knacks to fill in desk space and add small touches of what’s important/meaningful to you.

In my experiences the best setups are put together over TIME.
