Mountain View Travel Portrait

Use the uploaded reference image as the PRIMARY and STRICT identity reference.
Create a highly realistic vertical 9:16 photograph of the EXACT SAME PERSON from the reference image.
IDENTITY PRESERVATION IS THE HIGHEST PRIORITY:
Preserve the face with maximum possible fidelity to the reference image. Keep the exact same facial structure, face shape, forehead, eyebrows, eyes, eye shape, nose, lips, cheeks, chin, jawline, skin tone, natural facial proportions, hairline, hairstyle, and all recognizable facial characteristics. Do not change, redesign, beautify, smooth, reshape, slim, widen, age, de-age, or retouch the face. Do not generate a different person.
SUBJECT MUST REMAIN UNCHANGED:
Keep the same person, same body proportions, same pose, same hand positions, same facial expression, same hairstyle, same sunglasses, same clothing, same jacket, same hoodie, and same overall appearance as the reference image. Do not change the outfit or accessories.
ONLY CHANGE THE BACKGROUND:
Replace ONLY the original background with a beautiful realistic mountain landscape. Keep the person completely unchanged and naturally integrated into the new environment. Create large scenic mountains in the background, green forest-covered hills, distant valleys, clear blue sky, soft natural daylight, and a realistic outdoor travel-location atmosphere.
COMPOSITION:
Keep the same overall framing and subject placement as the reference image. Vertical 9:16 portrait composition. Full natural photographic perspective, realistic depth of field, authentic camera optics, natural sunlight and shadows.
REALISM:
Ultra-photorealistic, high-resolution photography, natural skin texture, realistic hair strands, realistic fabric texture, accurate lighting, natural colors, subtle depth of field, professional travel photography.
IMPORTANT:
The reference person is NOT to be modified. Change ONLY the background. No face alteration, no identity change, no outfit change, no pose change, no body reshaping, no beauty filter, no artificial facial features, no cartoon effect, no AI-looking skin.
OUTPUT: Vertical 9:16 only.
