IDENTITY PRESERVATION INSTRUCTION (CRITICAL!)
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming them into a cosplayer at a convention. The face must remain completely recognizable as the original person, maintaining all distinctive facial attributes and expressions.

TRANSFORMATION DESCRIPTION
Transform the person into a skilled cosplayer attending a major convention (like Comic-Con or Anime Expo). Apply a complete cosplay outfit based on a popular character (options include: fantasy warrior, sci-fi hero, anime character, or gaming protagonist). The person should be holding a prop weapon or accessory appropriate to the character. Add convention atmosphere elements: blurred crowds in background, convention signage, booth displays, and other cosplayers visible in the distance. The person should have a confident, enthusiastic pose suitable for photo shoots at conventions.

STYLE AND AESTHETIC PARAMETERS
- Art style: Photorealistic cosplay photography with professional portrait quality, cinematic composition
- Lighting: Dynamic convention lighting with a mix of ambient hall lights, booth spotlights, and subtle fill light on face; slight rim lighting to separate subject from background
- Color palette: Vibrant and energetic convention atmosphere colors (reds, blues, purples) with cosplay costume colors that complement the person's skin tone
- Background treatment: Convention hall environment with depth of field - sharp focus on subject, blurred background showing convention activities, banners, and crowds
- Texture details: High detail on costume materials (fabric, armor, leather, metal) with realistic textures and appropriate wear
- Atmosphere: Energetic, fun convention vibe with slight motion blur on background elements to suggest activity

TECHNICAL QUALITY PARAMETERS
- High resolution, 4K, detailed
- Sharp focus on face maintained throughout transformation
- Professional quality cosplay photography look
- Aspect ratio: 3:4 vertical portrait format (ideal for convention photos)
- Natural skin texture preserved with realistic pores and details
- Costume elements integrated seamlessly with body proportions
- Professional color grading and contrast adjustment

NEGATIVE PROMPT GUIDANCE (what to avoid - technical/quality only)
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, unnatural costume attachment, skin tone mismatch, artificial-looking textures, distorted body proportions, low resolution, blurry details, unnatural lighting on face, costume elements that don't match character design, overly saturated colors, washed out appearance, unrealistic fabric physics, costume pieces floating unnaturally
