**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 applying the Halloween costume transformation. The facial identity must remain 100% recognizable and natural.

**TRANSFORMATION DESCRIPTION**
Transform the person into a festive Halloween costume character. Apply one of these costume styles: Classic Witch (with elegant black hat, flowing dark robe, mystical accessories), Vampire (with aristocratic cape, formal Victorian attire, subtle fangs), Skeleton (with stylized skeletal body suit, dia de los muertos face paint elements, or subtle bone motifs), Pumpkin King (with pumpkin-themed clothing, warm orange and brown tones, festive accessories), or Ghost (with ethereal white flowing fabric, translucent spectral elements, vintage sheet ghost aesthetic). The costume should look naturally integrated with the person's body and suit their personality and body type. Keep the transformation fun and festive, not scary or grotesque.

**STYLE AND AESTHETIC PARAMETERS**
- Art style: Photorealistic, cinematic quality with professional portrait photography standards
- Lighting: Dramatic Halloween atmosphere with warm orange candlelight, cool moonlight, or moody shadow play. Soft key lighting on face to preserve features, atmospheric rim lighting for depth
- Color palette: Rich autumn tones (deep oranges, purples, blacks, midnight blues) or high-contrast monochrome. Colors should complement the person's skin tone and hair color
- Background treatment: Halloween-appropriate setting - pumpkin patch, spooky forest with fall foliage, Victorian gothic interior, haunted mansion foyer, or mystical night sky with full moon. Background should be slightly blurred (bokeh) to keep focus on the person
- Texture details: High detail on costume fabrics (velvet, silk, linen), accessories (metal, wood, fabric), and face paint/makeup if applied. Natural skin texture preserved

**TECHNICAL QUALITY PARAMETERS**
- High resolution, 4K, detailed
- Sharp focus maintained on face and eyes
- Professional portrait quality with natural skin texture
- Cinematic composition with rule of thirds
- Natural depth of field with subject in sharp focus
- Aspect ratio: 4:5 (portrait) or 1:1 (square) recommended
- Master quality, award-winning photography style

**NEGATIVE PROMPT GUIDANCE**
Avoid: distorted facial features, unrealistic costume proportions, blurry face, loss of facial likeness, unnatural skin texture changes, costume elements covering the face completely, low quality artifacts, pixelation, unnatural lighting on face, mismatched body proportions, costume looking like a cheap overlay
