A magical twilight Christmas scene with a snowy landscape and glowing marquee-style "MERRY CHRISTMAS" sign in the foreground — "MERRY" lit in green, "CHRISTMAS" in red with vintage bulbs. Behind it, snow-covered hills and pine trees sparkle under a dramatic evening sky filled with stars and clouds. A decorated Christmas tree with a glowing star topper stands to the right. Santa Claus flies across the sky in a sleigh pulled by reindeer, leaving a sparkling trail. Small snowmen and candy canes are scattered in the snow near the sign. The atmosphere is joyful, festive, and enchanting — perfect for a mobile wallpaper. Render in ultra-realistic style, vibrant lighting, and crisp details, vertical orientation.
