Luxurious Winter Bedroom Retreat

Generate a hyper-realistic photo of a luxurious bedroom with a large window showcasing a serene winter landscape. The room features a modern bed with a tufted headboard, white and gray bedding, and a gray blanket. A gray armchair sits beside a Christmas tree decorated with lights on the right side. The ceiling has a large crystal chandelier and recessed lighting. The floor is made of light-colored wood in a herringbone pattern, with a gray rug under the bed. The window has sheer curtains and a view of snow-covered evergreen trees and mountains. The overall atmosphere is calm and sophisticated, with a touch of festive cheer. The image should be rendered in high detail, with realistic materials, shadows, and natural lighting.
