I would sit the vase on the floor. beside the chest...looks too tall on there to me. I would hang some sheer curtains on the windows and done. You did very well with your decorating.

Thank you so much for the advise ! There are horizontal blinds on the windows which you probably can’t see. However, sheers on the windows may soften the room up a bit.

I'd pull the rug from under the bed so it covers more of the floor that is not under the bed.

The 'XOXO', might look okay(vertically? 2 over 2?) on the blank wall to the left of the door and you'd then add some artwork over the bed that has a bit of color in it.

I think your room looks wonderful. A bedroom is such a personal space. All that matters is how you feel about it. It looks inviting and serene to me❣️

The vase is bigger so I think it will be replaced by another and the rug under your bed is not seen well so you have to pull out it outside your bed. For more decoration, you can use a hanging plate and a decorative lamp which gives you the best feeling about your bedroom. Overall your room is looking fabulous.
