Indonesian High School Girl Classroom Portrait

A realistic full-body portrait of a beautiful young Indonesian high school girl, approximately 16-17 years old, standing confidently in a classroom. She has long straight black hair falling past her shoulders with soft bangs framing her face, fair skin, gentle smiling expression looking directly at the camera, natural soft makeup. She is wearing a classic Indonesian SMA school uniform: white short-sleeved collared shirt, maroon V-neck knitted sweater vest with thin white trim around the neckline, grey pleated mini skirt that ends above the knees, white knee-high socks, and black casual sneakers. Her left hand is resting on her hip, right arm hanging naturally by her side, body slightly turned in a relaxed yet poised pose. Background: a large white classroom whiteboard filled with handwritten black marker mathematical equations about limits and trigonometry (visible formulas include lim cos 2x, lim (sin x + cos x), √2, π/4, etc.). Above the whiteboard is a wooden frame, a round analog wall clock showing around 10:10, and a framed official photo of the Indonesian president with the red-and-white flag. Grey concrete wall, white ceramic tiled floor, soft natural classroom lighting from the front-left, slight depth of field focusing on the girl. Photorealistic, highly detailed face and clothing textures, natural skin pores, realistic fabric folds on the vest and skirt, cinematic lighting, sharp focus, 8k resolution, shot on 50mm lens.
