A cozy cave-style bedroom built into a snowy hillside, with soft rounded clay-textured walls glowing warmly under dim lights. A large low-level bed fills the room, covered with beige and pink bedding, many plush toys, and fluffy pillows. Outside the small curved window, gentle snowfall sparkles under the moonlight. A soft yellow floor lamp glows beside the bed, with books and candles on a wooden shelf. Peaceful snow night mood, ultra-realistic, cinematic lighting, cozy aesthetic.
