I did an overall from my past setup, new desk, new chair, monitor arm, cable management trays. But it looks so bland and I really don't know what to do

I have no figurines except the one I already have on there.

I was thinking putting a pegboard maybe on empty wall but I really don't know.

The goal is to get it a bit more lively, maybe add some green to it you know. Plants and stuff. But I also want it to be utilitarian, like fill up empty spaces but have it serve a purpose.
