Wall colour all round, shelf with gold, white and silver frames, white and grey bedding - hate the writing on the wall but love the shelf with the photoframes and would have fun finding pictures for them :)
Maybe add an extra 'wardrobe' at the side of cupboard of 'M's' room to create the look of a double wardrobe-then the vanity unit area to the side. Also love the grown up silver look 💕
