When you make a design it is supposed to make people feel cozy or happy. Or look visually stunning. But this makes me feel confused. I am saying this with no intention to offend you. But why have you chose to make the walls black? And may I remind you that a penthouse apartment is supposed to be light? If the colors were different I would like it a lllllloooootttt more! Please understand this is just my opinion and I really don’t want to hurt your feelings. But please see mine and have a nice day

i feel that if you added maybe a pop of color or done black accents. but doing the all Dark Shades made it look small
