"Birthday Rooftop Celebration Portrait"

CRITICAL RULE #1 (read first, applies above all else): The face in the output MUST be the exact same person as the uploaded reference photo. Do not generate a new face, do not beautify, do not idealize, do not blend with a generic face. If you are unsure whether the face matches, default to making it MORE identical to the reference, not less. IDENTITY LOCK (exact match required): Match the reference photo exactly for: face shape and bone structure, eye shape/size/color/spacing, eyebrow shape, nose shape and width, lip shape and fullness, chin and jawline shape, cheekbone structure, skin tone and undertone, any visible marks, moles, or asymmetries. These are not suggestions — they are hard constraints. Zero deviation allowed. DO NOT COPY FROM REFERENCE (only these things should change): expression, eye gaze direction, head angle/tilt, and body pose should NOT match the reference photo — generate these freshly based on the scene below. To be clear: FACE IDENTITY = locked exactly. EXPRESSION/POSE/ANGLE = freely generated and different from the reference. EMOTIONAL INTENT (design goal): This should feel like a genuine milestone birthday moment — the kind of photo a guy would actually want for his birthday post, looking like his best real self, celebratory and confident, not overly done-up or fantasy-styled. LIGHTING SETUP (as a real photographer would dial it in): Key light — warm string of fairy lights and a soft sunset glow on a rooftop terrace, acting as a gentle warm key from camera-left at chest height. Fill — soft ambient dusk-blue sky light from above, gently balancing the warm key at close to a 2:1 ratio so shadows stay soft. Rim light — the fairy lights behind him create a delicate golden edge-glow along his hair and shoulder. Catchlights in his eyes should be warm and lively, picking up the string lights. LENS & OPTICS: Simulate an 85mm lens at f/2.0 — flattering facial compression, background rendered as soft creamy bokeh with blurred balloons, fairy lights, and a city skyline at dusk, gentle fall-off in sharpness away from the focal point, faint natural vignette at the corners. FILM/COLOR SCIENCE: Warm celebratory film response — highlights bloom softly rather than clipping, shadows lifted gently rather than crushed black, warm golden-amber midtones, natural true-to-reference skin tone — color grading must not shift his actual skin tone from the reference. Style: A smart-casual outfit (fitted shirt or bomber jacket, sleeves slightly rolled), minimal accessories (watch, simple chain) — the kind of look he'd actually wear to celebrate, realistic and relatable, not an exaggerated glam transformation. NEW POSE & ANGLE (must differ from reference, face identity unchanged): Standing near a balloon arch or fairy-light backdrop, one hand raised casually holding a small sparkler or a drink, body angled at three- quarters to the camera, head turned back over one shoulder toward the lens with relaxed energy. NEW EXPRESSION (must differ from reference, face identity unchanged): A genuine, confident laugh or warm open smile with eyes crinkled — the natural joy of someone celebrating a happy milestone, right after a photographer says "just enjoy the moment and look over at me," not a stiff copied expression. RETOUCH PIPELINE: Smooth tonal transitions while fully preserving fine pore-level texture and the reference face's exact proportions. No flattening, no waxy skin, no facial reshaping of any kind. FINAL VERIFICATION (mandatory self-check before output): Compare the generated face side-by-side against the reference photo's face shape, eyes, nose, lips, and jawline. If any facial feature does not match the reference person, discard and regenerate the face to match exactly — only the expression, pose, and angle are allowed to differ. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
