Portrait de salle de classe coréenne

Ultra-realistic portrait of a beautiful young Korean woman standing beside large classroom windows in an empty Korean classroom during daytime, posing naturally while looking directly at the camera with a soft gentle smile. One hand resting casually in her hair, relaxed confident posture, modern Korean fashion aesthetic. Wearing a fitted black ribbed long-sleeve scoop-neck top and light gray skinny jeans, minimal elegant styling. Long straight black hair with soft natural volume, flawless fair skin, subtle makeup, delicate necklace. Warm sunlight streaming through the tall windows, cinematic natural lighting, soft shadows, clean academic atmosphere, green chalkboard and South Korean flag visible in the background, shallow depth of field, highly detailed, realistic skin texture, DSLR quality, ultra sharp focus, cozy youthful mood, vertical composition, 3:4 aspect ratio.
