Thank you for the opportunity.
Firstly I changed the position of the closet to add space beside the desk to be used for any function you desire. and I think indirect light with false ceiling is much more suitable for the bedroom.
Secondly, I used one color palette with 2 type of wallpaper. You can choose any of them which is closer to your taste. Therefore, I rendered them both to give you the idea of how it would look like.
Hope you enjoy
