How to Write a Good Body Prompt (and What to Avoid)
The body prompt controls what the guest is doing in the drawing. The same prompt mechanic is used by da Vinci, Raphael, and Picasso — three of the AI Draw Me models that share the Subject / Type / Body controls.
The body prompt only needs to describe the idea you want the guest placed in — the model handles the drawing style, line art, and pen-friendly conversion on its own. Keep it short and concrete.
How a Good Prompt Is Built
A good body prompt is built in three layers, from simplest to most personal. Pick the level that fits the event.
1. Basic — just the concept
Start with the subject or activity in a few words. This is the simplest form and is often enough on its own.
Basketball Player
Chess Player
Riding a dragon
2. Add a scene — concept + relevant background
Take the basic concept and add a relevant background or surrounding scene.
Basketball Player with relevant background behind
Chess Player with relevant background behind
Riding a dragon with relevant background behind
3. Make it personal — concept + scene + sign with a name
Add a sign, banner, or jersey with the guest's name (or a brand) for a personalized touch.
Basketball Player with relevant background behind and a sign with the name "Boaz" on it
Chess Player with relevant background behind and a sign with the name "Boaz" on it
Knight riding a dragon with relevant background behind and a sign with the name "Boaz" on it
That is the level of detail the prompt should reach — describe the idea, the scene, and the personal sign. Nothing more.
Tip: For per-guest personalization, we recommend using the FMX Survey feature with Dynamic attributes inside the prompt — collect the guest's name (or other detail) during the session and have it injected into the prompt automatically, instead of hard-coding a single name.
Model-Specific Notes
The same body prompt produces different visual results depending on the model:
- da Vinci — Stylized caricature, bold personality, exaggerated features. Best when fun matters more than accuracy.
- Raphael — Minimal sketch, fewer lines, clean and fast. Best for high-volume events where speed matters.
- Picasso — Sketch family, same control set as da Vinci and Raphael, alternative artistic feel.
The prompt itself does not need to change between models. Test the same prompt across all three to see which artistic style fits the event best.
What to Avoid
- Drawing-style instructions ("line art", "pen style", "clean lines", "no shading") — the model handles all of this.
- Long structured prompts that stack pose, clothing, accessories, and constraints into one sentence.
- Photorealism or fine-detail requests — these are sketch/caricature, models.
- Multiple subjects when the event is configured for a single guest.
- Tiny text other than a short sign or name.
- Dense, busy backgrounds packed with many props.
Event Tips
- Test each prompt before the event with a real guest photo, on the model you plan to use live.
- Keep a few approved prompts ready for staff so the event operation stays consistent.
- If the drawing takes too long on paper, simplify the scene rather than adding style constraints.
