IDENTITY PRESERVATION INSTRUCTION: Using the uploaded photo as reference, preserve the person's exact facial features, body proportions, skin tone, skin texture, unique characteristics, and anatomical structure while applying tattoo designs. Maintain the original identity, facial identity, and recognizable physical attributes completely unchanged.

TRANSFORMATION DESCRIPTION: Apply professional tattoo designs onto the person's skin in the uploaded photo. The tattoos should appear as if naturally integrated into the skin with realistic texture, lighting, and shadows. Show tattoo styles such as: blackwork, traditional, neo-traditional, realistic, geometric, watercolor, line art, dotwork, or script lettering. Position tattoos naturally on visible skin areas (arm, shoulder, neck, face, leg, back, chest, or hand) based on the photo composition. The tattoos should follow the body contours and skin texture realistically.

STYLE AND AESTHETIC PARAMETERS:
- Photorealistic integration of tattoos onto natural skin
- Professional tattoo art style with clean lines and proper shading
- Skin texture remains visible and natural with pores and subtle variations
- Tattoo ink appears slightly raised/embossed for realistic healing look or flat and fresh
- Lighting should cast natural shadows from tattoo design onto skin
- Color palette: Black ink, grayscale, or color tattoos depending on design choice
- Background: Keep original background or slightly blurred for focus on tattoo
- High contrast between tattoo and skin for visibility
- Professional tattoo portfolio quality aesthetic

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on tattoo design and surrounding skin
- Professional quality tattoo mockup
- Aspect ratio: 1:1 (square) or 4:5 (portrait) recommended for best tattoo visibility
- Crisp tattoo edges with no bleeding or blurring
- Natural skin texture preservation
- Realistic shadow depth and dimension

NEGATIVE PROMPT GUIDANCE: Avoid: distorted facial features, unrealistic skin texture, blurry tattoo edges, loss of facial likeness, tattoo floating above skin, mismatched lighting on tattoo, pixelated design, unnatural proportions, tattoo scaling issues, skin tone mismatch around tattoo area, over-saturated colors, unrealistic shadows, loss of skin detail, artificial-looking ink
