Scan the room for any free points that can be used to add a nice light near the work/study desk.
Work or study time doesn’t have to be dull and small accessories like a table lamp can really add a bright element in a balanced manner.
Add a few planters to this area to have a feel of the outdoor.
Add some fun quotes to lighten the mood or some motivational quotes framed on the wall to get through those really testing days.
You can add some decals to the wall and look for some interesting seating poufs online to add extra seating and glamour in the room without blocking much space.
Take the liberty to add a color of your choice or even some bold print while adding accessories like a pouf to the room.
