A whimsical Christmas night scene set in a snowy landscape with rolling hills and pine trees adorned with glowing lights. A cozy wooden cabin with illuminated windows and smoke rising from the chimney sits nestled among the trees. Above the cabin, a full moon shines brightly in a star-filled sky, surrounded by hanging decorative lights and snowflakes. Santa Claus rides a sleigh pulled by six reindeer across the sky in front of the moon, leaving a sparkling trail behind. The atmosphere is magical and festive, with vibrant colors and enchanting details. Portrait orientation, cinematic lighting, holiday fantasy illustration style, perfect for mobile wallpaper.
