Ordinary Schoolgirl Street Snapshot | GPT Image 2プロンプトと調整メモ

A candid, realistic street photo of a {argument name="subject age" default="teenage"} Japanese schoolgirl walking outdoors in a modern city on a bright sunny day, framed as a vertical smartphone portrait from mid-torso up. She has long dark brown to black hair parted near the center and styled in low twin ponytails tied with dark bands, with soft natural strands and a clean youthful appearance. She wears a white button-up school shirt under a loose cream-white cardigan, a large navy blue ribbon bow at the collar with a small white floral or bunny-like pattern, and a dark shoulder bag strap crossing over one shoulder. She holds 1 white takeaway coffee cup with a black plastic lid in one hand. Her expression is neutral and ordinary, like an everyday snapshot, with a subtle documentary feel. Place her on a tree-lined sidewalk beside a glass-front building with reflections and interior shelving visible; in the blurred background include 3 other students in white shirts and dark skirts walking along the pavement. Use soft natural sunlight filtered through trees, gentle highlights on hair, shallow depth of field, realistic skin and fabric textures, slight bokeh, casual composition, and an authentic contemporary Japanese urban school commute atmosphere.
