Crafting better AI headshots – what prompts actually work?

I've been experimenting with AI headshot generators to create professional profile photos, and I'm hitting a wall with generic results. Most services give you decent photos, but they often lack that authentic, personal touch.

I've tried TheMultiverse AI Magic Editor and while the base quality is good, I'm wondering if there are specific prompting strategies that could improve the output. The standard "professional headshot" prompt gives me pretty generic corporate-looking results.

What I'm trying to figure out:

What specific adjectives or style descriptors work best for different professions? (e.g., "approachable" vs "authoritative")

Are there particular lighting or background prompts that consistently produce better results?

How do you balance specificity with leaving room for AI interpretation?

Has anyone created effective prompt templates for different professional contexts?

What's the difference between prompting for "LinkedIn professional" vs "creative industry professional"?

I'd love to see examples of successful prompts and learn what makes them work. Any prompt engineering insights for better AI photography?
