IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while integrating them into a Vietnamese travel scene. The person's likeness must remain 100% accurate and recognizable.

TRANSFORMATION DESCRIPTION:
Transform the photo into a professional travel portrait set in Vietnam. Place the person in an authentic Vietnamese location such as: Hanoi's Old Quarter with colonial architecture and lanterns, Ha Long Bay with limestone karsts and emerald waters, Hoi An Ancient Town with yellow walls and colorful lanterns, or a traditional Vietnamese village with rice terraces. The person should appear naturally integrated into the scene, wearing casual travel-appropriate clothing that complements the setting. The pose should be natural and candid, as if captured during actual travel. Include subtle atmospheric elements like soft morning light, gentle fog, or warm sunset glow that enhances the travel mood.

- Art style: Cinematic travel photography, photorealistic with artistic composition
- Lighting: Natural golden hour light or soft diffused morning light, creating warm and inviting atmosphere
- Color palette: Rich earthy tones, warm yellows from Vietnamese architecture, deep greens from tropical vegetation, vibrant pops of color from lanterns and local textiles
- Background treatment: Authentic Vietnamese locations with depth of field - slightly blurred background to maintain focus on the person while clearly showing the destination

- Details: Include subtle environmental elements like traditional Vietnamese architecture, tropical plants, water reflections, or local street life that feel natural and not cluttered
