Hi there! I found an Ideabook that may help you: https://www.houzz.com/magazine/guest-picks-little-kid-big-style-stsetivw-vs~1538405

If you are wanting to almost start over, I would paint in a soft blue or soft blue/green or soft green. These colors are restful, soothing and inviting. Wood floors will be great. I would get white bedding and maybe some colorful shams. White will work with anything else. Move the bed in the center of the wall. I would repaint the nightstand white and move it closer to the closet to be able to center the bed. Get another nightstand same height. Or get two new white taller night stands. You could get a small desk to go with the chair. Paint the chair white. Maybe window panels in a semi-sheer woven frint fabric. Place a dressing mirror on the back of the door. Take the colors from the drape for throw pillows on the bed. It will feel bright and fresh, yet restful. Something like this feeling Wall color and bedding

Your window is a main accent. And you need to make a start from its. I recommend you to do the follow: - open your window as much as possible. This will make the room larger; - decorate the window by asymmetrical or direct curtain (examples are below), starting right from the ceiling. It is best to use a solid color textile; - if your cabinet is not particularly necessary, I would have replaced it on the floor lamp; - on the other side, you can fold the high stack of books and use them as a decorative stand; - make a picture in passe-partout with glass and dark gray baguette frame. Add to it a vertical series of small monochrome photographs (eg sepia), and also complete passe-partout in pastel tones; - fur pillows should be replaced by textile pillows with dark gray graphic pattern; - it will be better the other pictures on the walls to remove

Adding width BEHIND THE BED - with a headboard (which doesn't have to be a "headboard"; it could be fabric, collection of mirrors, collection of pictures, a farm gate!, small chairs or stools) across the entire width. Matching bedside tables/bookcases/chests/ with LAMPS - useful storage for extra books, extra bedding, etc. CURTAINS always warm up a room. People will always feel colder away from home - provide an extra blanket or duvet to add to the bed. I notice there is no WARDROBE. Not really necessary for overnight guests (provide hooks on the back of the door) but useful for storing your out-of-season coats, etc. There is plenty of room behind the door. Buy one on eBay and paint it to suit your colour scheme.
