Mountain Bike Portrait

Use the uploaded photo as the single and exclusive facial identity reference. Absolute face lock. Preserve 100% exact facial structure, bone proportions, jawline, cheekbones, eye shape, eyelid fold, eyebrow thickness and direction, nose width and tip shape, lip shape, skin texture, natural pores, natural asymmetry, hairline, sideburns, beard density (if present), and overall head shape. No beautification, no smoothing, no stylization, no facial reinterpretation. Create a photorealistic outdoor portrait of the same person sitting casually on a black sport motorcycle parked on a curved mountain road. Subject positioned slightly left of center, torso angled slightly toward camera, head turned naturally toward lens, relaxed neutral expression with subtle seriousness. Wardrobe: sky-blue V-neck knit sweater layered over a crisp white button-down shirt with visible collar and extended cuffs, loose black trousers. Fabric texture realistic with natural folds and weight. Environment: winding mountain road with guardrail on the right side, steep hillside with grass and shrubs on the near side, layered misty mountains in background. Low clouds hugging the mountain ridges. Overcast weather. Cool natural color palette. Lighting: soft diffused daylight from cloudy sky, no harsh shadows, balanced exposure, realistic skin tone. Subtle atmospheric haze in background for depth. Shallow-to-moderate depth of field, subject sharp, background slightly softened but still detailed. Camera: vertical 4:5 or 9:16 composition, eye-level angle, 50mm lens look, natural perspective (no distortion), high-resolution DSLR realism, true-to-life colors, cinematic but grounded color grading. Critical rules: Face unchanged 100%. No AI-generated facial drift. No stylization. No exaggerated jawline or eye enlargement. Maintain natural skin texture and real-world lighting physics. Keep proportions accurate and human-realistic. Ultra-detailed, authentic photography aesthetic. 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.
