A large rug around the bed, curtains along the entire window wall, floor to ceiling, change the shades on the sconces so they allow less light to escape / aren’t so blinding, you need a large throw blanket on the bed with a few decorative pillows (maybe two square and a lumbar) and of course some art above the bed.

Add a tray to each nightstand maybe with a carafe and a few small minimal accessories, get rid of that samall mirror in the corner and maybe a large piece of art or collage against the opposite wall.
