角色设定 GPT Image 2 提示词：Realistic McDonald's Selfie Portrait

A highly realistic casual smartphone selfie taken indoors at a McDonald's restaurant in Asia, framed as a chest-up portrait of a young man seated at a table. The camera is held slightly above table height at arm’s length, creating a natural front-facing selfie perspective with one forearm extending toward the lens. The subject wears a black T-shirt with a small white electric vehicle brand logo on the left chest, has short straight black hair, thin dark eyeglass frames partly visible, and rests one hand lightly against his chin in a relaxed pose. His face is fully obscured by a large solid rectangular blur block in the center, preserving privacy while leaving the hair, ears, jawline edges, and glasses arms visible. In the lower left foreground sits 1 white McDonald's paper drink cup with a lid and a white straw, cropped by the frame. The background shows the restaurant counter area with warm ambient lighting, 1 large red wall panel on the left featuring the yellow McDonald's arches and the white slogan “i’m lovin’ it” with Chinese text below, 4 illuminated digital menu boards across the top displaying burgers, fries, combo meals, prices, and Chinese text, plus 2 people in the background near the counter, one facing away with a backpack and another partially visible behind the register. Use natural color balance, slight indoor grain, realistic reflections, shallow to moderate depth of field, and the candid look of an unstaged social media snapshot.
