A 4K ultrarealistic portrait of a young girl around 15-17 years old, celebrating Christmas with a joyful and festive vibe. She is of mixed ethnicity, with warm brown skin, and her hair is styled in loose, natural curls that cascade down her shoulders. She wears a cozy, oversized red hoodie with white snowflake patterns, paired with sleek black athletic shorts. Her outfit is accessorized with a delicate silver necklace and matching hoop earrings. The girl stands confidently, her posture relaxed yet dynamic, one hand resting on her hip while the other playfully holds a small, glittering Christmas ornament. Her facial expression is radiant, with sparkling hazel eyes, rosy cheeks, and a bright, toothy smile that exudes happiness. The background is a beautifully decorated Christmas room, featuring a large evergreen tree adorned with twinkling lights, shiny ornaments, and a golden star on top. Soft, warm lighting illuminates the scene, casting golden highlights on her hoodie and creating a cozy, inviting atmosphere. The textures are highly detailed, from the fuzzy fabric of the hoodie to the reflective surface of the ornaments. The composition is framed in a mid-shot, capturing her full outfit and expressive face, with a slight upward angle to emphasize her youthful energy and festive spirit. The overall mood is warm, cheerful, and full of holiday joy.
