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 transforming the image into a sticker format. The subject's recognizable identity must remain intact and clear throughout the transformation.

TRANSFORMATION DESCRIPTION:
Transform the uploaded photo into a high-quality digital sticker suitable for Telegram and WhatsApp. The sticker should feature the person's face as the main subject, rendered in a clean, cartoonized style with smooth, bold outlines. The background must be completely transparent to allow for seamless integration into messaging apps. The sticker should have a playful, expressive quality while maintaining the person's true appearance.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Semi-realistic cartoon sticker style, similar to popular Telegram sticker packs, with clean vector-like lines and smooth color fills
- Facial rendering: Maintain realistic facial proportions while applying a subtle cartoon filter that enhances features without distorting them
- Line work: Clean, bold black outlines around the head and shoulders, with thinner lines for facial details
- Colors: Vibrant, saturated colors that pop against the transparent background; skin tones should remain natural and flattering
- Lighting: Soft, even lighting that eliminates harsh shadows, creating a bright and cheerful sticker appearance
- Expression: Keep the original facial expression or enhance it to be more expressive and sticker-appropriate
- Background: Pure transparent background (alpha channel) with no elements, shadows, or gradients
- Size and composition: Face centered and occupies 60-70% of the frame, with shoulders visible for context

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face and key facial features
- Professional quality sticker artwork
- Clean edges with no artifacts or fuzzy borders
- Consistent line weight and color application
- Perfect for 512x512 pixel sticker format (Telegram/WhatsApp standard)
- Anti-aliased edges for smooth appearance at any size

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, messy or broken outlines, transparent elements that should be opaque, opaque elements that should be transparent, color bleeding, pixelation, low resolution, text or watermarks, extra limbs or body parts, unnatural skin tones, excessive cartoon distortion that removes identity

ADDITIONAL TIPS:
- For best results, use a photo with clear facial features and good lighting
- The prompt works with both close-up portraits and headshots with shoulders visible
- If you want specific sticker elements (hats, accessories), mention them in the customization section
- For multiple stickers from the same person, use the same base photo with different expressions
