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 transformation. The person's identity must remain 100% recognizable.

TRANSFORMATION DESCRIPTION:
Transform the photo to show the person holding a guitar naturally in their hands. The guitar should be a realistic acoustic or electric guitar (user can specify) held in a comfortable, musician-like pose. The hands should be positioned naturally on the guitar neck and body, with fingers resting on the frets or strings realistically. The guitar should integrate seamlessly with the person's body proportions and current clothing.

STYLE AND AESTHETIC PARAMETERS:
- Art style: Photorealistic, cinematic portrait quality. The image should look like a professional studio photograph or a high-quality candid shot.
- Lighting conditions: Dramatic yet natural lighting that highlights both the face and the guitar. Soft key light on the face, with subtle rim lighting to separate the subject from the background. If the original photo has specific lighting, maintain that consistency.
- Color palette and mood: Rich, vibrant colors that complement the guitar's wood tones and the person's skin tone. Warm, inviting atmosphere suitable for a music theme. Slightly desaturated background to keep focus on the subject and instrument.
- Background treatment: Keep the original background if possible, but slightly blurred (bokeh effect) to emphasize the subject and guitar. If the original background doesn't fit, replace with a subtle music-themed or neutral studio background that doesn't distract.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face and guitar details
- Professional quality, studio photography standards
- Natural skin texture preserved
- Guitar wood grain and metallic details rendered with high detail
- Aspect ratio: 1:1 (square) or 4:5 (portrait) recommended
- No visible artifacts or AI generation errors

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic hand positions, blurry face, loss of facial likeness, unnatural guitar proportions, floating objects, extra fingers, mutated hands, extra limbs, disfigured guitar, low quality, pixelated, watermark, text, signature, cropped image, bad anatomy, unnatural lighting on face

ADDITIONAL TIPS FOR BEST RESULTS:
- For best results, use a photo where the person's hands are visible or partially visible
- You can specify acoustic or electric guitar in your additional context
- Mention desired pose or guitar color in additional context if you have preferences
- The prompt works best with front-facing or slightly angled portraits
