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 a grunge aesthetic. The person's identity must remain fully recognizable and clear.

TRANSFORMATION DESCRIPTION:
Transform the subject into a grunge style portrait. The person should be wearing typical grunge attire such as a flannel shirt, ripped jeans, or a vintage band t-shirt. The image should have a raw, unpolished, and slightly rebellious vibe. The grunge style should be integrated naturally into the person's appearance and the overall composition.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Photorealistic with a gritty, film-grain texture. Cinematic and moody.
- Lighting: Low-key, dramatic lighting with high contrast. Use shadows to create depth and mystery. A single light source or soft window light is ideal.
- Color Palette: Desaturated colors, muted tones, earthy shades (browns, greens, greys). Slightly cool temperature to enhance the moody atmosphere.
- Background: Urban decay, brick walls, alleyways, or a dimly lit room. The background should be blurred (bokeh) to keep focus on the subject but maintain the gritty environment.
- Texture: Add film grain, slight noise, and a raw texture overlay to simulate analog photography.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face
- Professional quality
- Aspect Ratio: 3:4 or 1:1 (portrait orientation)

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted features, unrealistic proportions, blurry face, loss of likeness, over-saturated colors, polished/commercial look, cartoonish elements, anime style, excessive digital noise, bad anatomy, deformed eyes, extra limbs.
