Ultra-realistic 8K DSLR portrait of a 2-year-old girl with long wavy hair, wearing a full Santarina Christmas costume from head to toe (red velvet dress with white fur trim, matching hat, festive accessories). She is in a snowy landscape like Lapland, riding on a wooden sled with a gentle reindeer beside her. Close-up shot with the girl looking directly at the camera, cheerful happy vibes, soft natural winter lighting, detailed snowflakes, rich textures in the Santarina outfit and reindeer fur, shallow depth of field, highly detailed skin tones and fabric, cinematic color grading, photorealistic.
