The Secret Sauce: Professional Prompting Tips
✅ Do This

- Specify "preserve identity" or "maintain authentic features"
- Ask for "professional" or "polished" results
- Include "no plastic smoothing" or "keep skin texture"
❌ Avoid This
- Words like "dramatic," "major," or "significant"
- Multiple conflicting requests in one prompt
- Overly technical terminology
- Requests that alter bone structure
Common Mistakes and Quick Fixes
Problem: Face looks "plastic" or over-smoothed
Solution: Add "preserve natural skin texture" to your prompt
Problem: Features look distorted
Solution: Restart the session and use gentler language like "very subtle"
Problem: Identity drift (you don't look like yourself)
Solution: Always include "preserve identity" or "maintain facial features"
Problem: Inconsistent results
