Photorealistic action shot of one beautiful Japanese high scoll girl sprinting at full speed in a relay race during a nostalgic Japanese sports festival. Vertical 2:3 composition, single subject only. appearance: dark chocolate-brown shoulder-length layered bob, soft natural bangs, warm brown eyes, delicate oval face, softly rounded cheeks, a small refined nose, glossy natural pink lips, and a bright determined expression. She must clearly look like an adult woman, with mature facial anatomy and natural adult body proportions. Never childlike, never teenage-looking. She is wearing a retro Japanese sports-day outfit: a fitted white athletic gym T-shirt and classic navy-blue bloomers, white socks, and running shoes. The outfit is wholesome, athletic, nostalgic, and fully clothed. Show her sprinting at maximum speed while gripping a relay baton tightly. Capture the exact moment of explosive forward motion: long stride, powerful leg extension, one arm driving forward, the other holding the baton, hair flying backward, fabric and motion lines emphasizing speed. Use a bold, dramatic composition with a low-angle or diagonal perspective, as if the camera is very close to the track. The framing should feel dynamic and immersive, with strong motion blur in the background. Background: sunny school athletic field, running track lanes, colorful festival flags, white tents, blurred spectators. Bright daylight, energetic atmosphere, vivid but natural colors, realistic skin texture, high-detail sports photography style. Emphasize speed, impact, athletic energy, and motion. Make it feel like a split-second sports photograph captured during an intense relay race. Negative: child, little girl, teenage appearance, loli, oversized head, short cropped hair, very short bob, extra people, sexual pose, revealing clothing, anime style, exaggerated anatomy. Freeze the most powerful instant of acceleration, with intense forward momentum and cinematic motion blur. Make the bib number on her chest clearly visible, and let the speed lines stream backward to strongly emphasize the sense of sprinting. Intense dynamic speed lines radiating backward from her body, dramatic manga-style action streaks, powerful motion blur, explosive sense of acceleration. Heavy perspiration from intense sprinting, realistic beads of sweat covering her forehead, cheeks, neck, arms, and legs, glistening sweat on her skin, tiny sweat droplets scattering through the air. Visible rapid breathing, slightly parted lips, breathless expression, mouth open as she exhales forcefully, realistic physical exhaustion, flushed cheeks, determined eyes, hair streaming backward in the wind.
