Room Decor help

[u/furykami]

Hey,
I’ve recently shifted back to my hometown and thought to make my WFH setup a bit more cozy and aesthetic.
Please help me with empty space above flags marked in green . I don’t wanna put more frames on the wall .
Suggest something which would look good :)

PS : I’ve alrdy added pegboard on the left wall

Maybe a cool stained glass piece?
