A festive winter scene featuring three cheerful holiday characters standing together in a snowy outdoor setting. From left to right: a cartoon-style Santa Claus in a traditional red suit with white fur trim, a smiling snowman with a red knit hat, red scarf, black buttons, and a carrot nose, and a friendly reindeer wearing a red-and-white striped scarf and fuzzy leg warmers. The background features softly blurred pine trees with twinkling lights and gently falling snowflakes. The atmosphere is vibrant, whimsical, and heartwarming. The composition is vertical and centered, optimized for mobile wallpaper.
