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 them into a professional cyclist or biker. The facial identity must remain 100% recognizable and match the source photo perfectly.

TRANSFORMATION DESCRIPTION:
Transform the subject into a dynamic cyclist or motorcycle rider wearing professional athletic gear. Apply a high-quality cycling jersey and bib shorts or a sleek motorcycle racing suit depending on the desired style. Add a modern aerodynamic helmet (road bike style or racing helmet). The person should be in an action pose: either cycling intensely on a scenic road or posing confidently with a high-end bicycle or motorcycle. The expression should be determined and focused, suitable for a sports portrait.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Photorealistic, high-definition sports photography. Cinematic and dynamic.
- Lighting: Natural sunlight with golden hour warmth or dramatic studio lighting with rim lights to highlight the gear and helmet contours. Sweating skin texture should look realistic.
- Color Palette: Vibrant, energetic colors for the cycling gear (reds, blues, blacks, neon accents) or sleek matte blacks and metallics for motorcycle gear. Contrast between the athletic outfit and the background.
- Background: Blurred scenic mountain roads, urban cityscapes at dusk, or a professional cycling studio with motion blur effects to imply speed. Keep the background professional and non-distracting.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed, ultra-sharp.
- Sharp focus on face and eyes; the helmet can be partially lifted or worn but face must be clearly visible.
- Professional quality, studio-grade photography.
- Aspect ratio: 2:3 (vertical portrait) or 16:9 (cinematic wide).
- Highly detailed fabric textures on the jersey and suit; realistic helmet material reflections.

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, blurry face, loss of likeness, unrealistic proportions, cartoonish style, low quality, pixelated image, deformed hands, extra limbs, helmet covering the entire face (unless specified), text on clothing, watermark.

ADDITIONAL STYLING NOTES:
- If the user wants a specific type of cyclist (e.g., Tour de France professional, Mountain Biker, MotoGP racer), include those keywords.
- For helmet options: specify "racing helmet with visor up" or "road cycling helmet" to ensure face visibility.
- For mood: "intense competition focus" vs. "casual bike ride smile".
