Ultra-realistic 8K DSLR portrait of a 2-year-old boy wearing a full Santa costume from head to toe (red velvet suit, white fur trim, Santa hat, little boots, festive details). He is in a snowy landscape like Lapland, riding on a wooden sled with a gentle reindeer beside him. Close-up shot with the boy looking directly at the camera, joyful happy vibes, soft natural winter lighting, detailed snowflakes, rich textures in the Santa outfit and reindeer fur, shallow depth of field, highly detailed skin tones and fabric, cinematic color grading, photorealistic.
