for the bedroom layout, i dont put L-shaped Wardrobe as your request there.. actually it is still possible to put it there, but first, it just left little space between wardrobe and bed.. i think it's too narrow and not comfortable.. second, it makes your bedroom look so full and narrower.. that's why i choose bigger wardrobe there and add some wall shelves and storage. i see before that you dont have dressing table, so i add that one too..
then, for the colour of the room, i choose blue
as from psychology of colour, blue gives calm impact, its good colour for relaxation and i think it's the right colour for bedroom.
Hope you like the design
Thank you!! :)
