I happen to like the kind of shades that you can pull from the top down or from the bottom up so you can still have privacy for dressing but also light in the room. You can get them in light-filtereing or black out, and in nice colors or just neutrals.

Sconces over the nightstands would be nice. So would lamps on the tables

I think a narrow upholstered bench at the foot of the bed would be nice, maybe especially one with a bright patterned tropical look. Maybe a couple of teal accent pillows?

I can’t tell what the subject of your art work is, but would this bench fit with it?

I meant to add something about sconces: Be sure you position them where you can easily turn them off once you are in bed. Not too high, and get the kinds that have switches on them.

I’m thinking that a chocolate brown bedding set might be very nice in your room, and maybe with this accent pillow

If you switch to dark bedding, maybe a natural wicker bench would lighten the feeling.

You could use some texture.

Could have blackout cellular, and soft flowy semi- or sheer over.

Or sheer cellular, and heavy curtains. In small room I picture the former.
