I find your room really, really cosy! It’s lovely. Although it is neutral you have light and dark elements which stop it looking boring. It just looks like the walls have been forgotten, so some art above the bed, or on any other blank walls would look great. A lightweight canvas rather than a heavy framed print. Panelling is beautiful but unless you do it yourself then it can be pricey.

I would suggest starting by decluttering and organising your space and using baskets/boxes to organise items that don't need to be out in the open. Create dedicated areas for where things go (desk things with only desk things etc), If you could take a picture of the other side of the wall (closest to the wardrobe) then perhaps we could help more. Opening curtains does help with lighting as well.

It is hard to be sure but I don’t think you can move the large storage anywhere else so you are kind of stuck with your current arrangement. If you were prepared to block the window where you have your table you could maybe move the large cupboard there then have table on your left when you come in and keep bed where it is. It looks like you have lots of books to store I know you said you do t want any new furniture but if you got rid of the small desk I. The corner and replaced with a tall bookshelf you would be able to get all the books in one place. I agree a good sort out is the first step

Hi! These are photos of my bedroom and living room. I would love to redesign both spaces in a romantic and artistic style. I’m looking for ideas and suggestions to help me create a cozy, dreamy, and elegant atmosphere. What kind of items, furniture, or colors should I add to achieve that? Any advice is appreciated! Thank you!
