"Human" means nothing to the AI. Every other race has a visual hook — elves have ears, dwarves have beards, tieflings have horns. Humans have nothing. You have to build the visual identity from scratch.
Specify Ethnicity
AI defaults to a narrow demographic unless directed otherwise. Be precise: "deep brown skin" not "dark-skinned." "Wind-chapped fair skin" not "pale." Reference real-world anchors: "East Asian features", "Mediterranean complexion", "West African build."
The Three Levers
1. Age
The strongest differentiator. A 20-year-old and a 60-year-old produce completely different portraits.
- Young: "smooth skin", "bright eager eyes", "slight build"
- Prime (30s-40s): "defined features", "first gray hairs", "laugh lines"
- Veteran (50s-60s): "deep weatherlines", "salt-and-pepper hair", "knowing tired eyes"
- Elder: "deeply lined face", "thin white hair", "stooped posture"
2. Profession
Profession shapes the body. A blacksmith has different hands than a scribe.
- Soldier: "military bearing", "cropped hair", "alert scanning eyes"
- Scholar: "ink-stained fingers", "squinting eyes", "pale from indoor life"
- Merchant: "well-fed build", "calculating gaze", "fine clothing with travel wear"
- Sailor: "sun-weathered skin", "wind-tangled hair", "lean wiry build"
3. Scars and Marks
Nothing makes a portrait more memorable. Add one or two:
- "jagged scar across left cheek"
- "ritual tattoos covering neck and jaw"
- "broken nose healed crooked"
- "heterochromia — one brown eye, one blue"
Prompt Structure
[Age + ethnicity] + [Distinctive feature] + [Profession markers] + [Clothing] + [Expression] + [Setting]
Example: "weathered 50-year-old human man with deep brown skin and a jagged scar bisecting his left eyebrow, salt-and-pepper close-cropped hair, battered leather brigandine over a faded gambeson, weary but vigilant expression, stone battlements at dusk, cold blue twilight, detailed fantasy portrait"
Troubleshooting
| Problem | Fix |
|---|---|
| Stock photo look | Add scars, specific age, profession, ethnicity |
| Looks modern | Add "medieval", "fantasy", "period clothing" |
| Too clean / perfect | "weathered", "scarred", "calloused", "sun-damaged" |
| Boring expression | "suspicious glare", "weary half-smile" |
