Hey! Since your bed is in the corner you could prop up your cushions in that corner so it’s like a cosy sofa during the day. Get a nice bedside table for next to your bed with a cute little lamp and move the storage you have next to your bed to someplace else. Remove the stool and switch it for a cute footstool or pouffe maybe?
I’d recommend keeping the room fairly neutral and just do pops of colour with accent cushions, bedding and maybe a nice rug! Good luck 🙂
