Chambre de penthouse de luxe face à une ligne d’horizon cosmique lumineuse

A serene luxury penthouse bedroom overlooking an infinite cosmic skyline. Outside, glowing amethyst clouds surround a brilliant silver moon while distant stars sparkle across deep navy space. Interior lighting remains minimal, with only a warm table lamp illuminating elegant linen sheets, black marble flooring, and contemporary décor. Gentle curtains flow inward from an open window. Rich cinematic shadows, dreamy atmosphere, ultra-realistic reflections, HDR, masterpiece
