Prompt
Use the uploaded photo as the reference for me and my friends; everyone shown has agreed to this edit. Preserve each person's recognisable face, natural skin tone, hairline and body proportions as closely as the model permits; check the result against the reference. Scene: friends on a city rooftop at blue hour, sitting on plastic chairs and an upturned crate with cutting-chai glasses, the lavender sky and city lights behind. Pose: mid-conversation and laughing, one person raising a glass. Clothing: the clothes from the photo. Light: direct flash on the group, soft ambient blue-hour light, a few warm windows below. Style: candid flash photo, soft colours, gentle grain, natural skin texture, relaxed end-of-day feeling. Format: vertical 9:16 Avoid: changing anyone's face or identity, adding or removing people, sitting on the edge, extra fingers, text, logos, watermarks.
