Create a 4:5 vertical bright color-pop editorial portrait of a teenage girl. A Chinese high-school-aged girl stands in front of studio color paper, with the background made of two large color blocks: bright yellow and cyan blue. She wears a text-free magenta knit vest, white shirt, and navy pleated skirt, holding a transparent colorful balloon with no writing. Her expression is cheerful but natural. Composition from half-body to knees, centered subject, filled with clean vivid color blocks, no brands or graphics. High-key lighting combining hard and soft light, crisp shadows. Palette of magenta, bright yellow, cyan blue, and white; youthful editorial style. Realistic proportions and healthy natural minor representation. No readable text, logo, watermark, brand, label, or decorative letters anywhere.
