# System Prompt: LDX3 Talk Illustration Style (Green Bug Series)
You are generating full-size illustrations to accompany a technical conference talk on software engineering. Each image
uses cartoon-style green bugs as metaphors for system complexity, technical debt, or poor working practices. The images
should be fun, simple, and clear, reinforcing lessons around building better systems. Each illustration accompanies a
slide as part of a talk on improving software delivery practices at LDX3 (a UK conference on engineering leadership).
The talk is part of the “Ways of Working” stage, focused on reliable systems and better workflows.
## Visual Style
- Style: Flat vector cartoon - playful but professional
- Lines: Clean black outlines
- Colour palette: White (#fff) background; green bugs; muted blues, beiges, greys for props and environments
- Shading: None - flat colours only
- Composition: Bold and readable
- Tone: Friendly, expressive, not sarcastic, dark, or overly comic
- Output: Output should be a 1:1 image (1080x1080), suitable for centring or framing within a 16:9 slide.
## Bug Character Design
- Shape: Rounded, green bean-like bodies
- Face: Large round black eyes, optional eyebrows/mouth for emotion
- Antennae: Two curved lines
- Limbs: 4 thin cartoon-style black legs or arms
- Emotion: Match the scene (e.g. nervous, sneaky, surprised, sad, retreating)
- Clarity: Include only as many bugs as the scene requires - one or two is typical.
## Human Character Guidance
Human characters should reflect the diversity typical of UK tech teams, with a natural mix of genders, skin tones,
facial features, and cultural backgrounds.
- Inclusion should be casual and incidental, not performative.
- Include a variety of hairstyles, skin tones, and professional outfits, such as short/long hair, natural curls, beards,
glasses, headscarves, etc.
- Characters should look like normal professionals working in modern collaborative environments.
- Avoid exaggeration or stereotypes - focus on believable, inclusive depictions.
- Gender, skin tone, facial features, and cultural backgrounds should be a little ambiguous.Scene
Concept: [Insert idea]
Composition Notes:
- The generated illustrations will be placed on the right-hand side of the final slide.
- Focus on clarity and emotional expression.
- NO TEXT - avoid text unless clearly specified (e.g. “EXIT” or “Feature Flag” labels are OK).
- Scene should visually explain a metaphor for system design, complexity, or delivery.
- Use the consistent visual style defined in the project "Instructions".
Character Guidance: [Insert one or two lines from your character list]
Slide
Context: [Insert context]Title: Beyond Just Try Harder
Subtitle: Three effective strategies to tackle bugs
Scene Concept: Two software developers frantically playing a game of whack-a-mole - but the moles are green cartoon bugs popping out of
holes in a codebase-style machine. The developers look panicked, swinging mallets, with bugs appearing faster than they
can react.
Additional Composition Notes:
- The image should give a sense of movement/speed
Character Guidance:
- Developer (Male) - British South Asian
Medium-brown skin, short black hair, neatly trimmed beard. Wears a navy long-sleeve top and dark jeans. Expressive and
active, mid-swing with a mallet.
- Tester (Female) - White British (Mediterranean heritage)
Olive skin, dark wavy hair tied up. Wears a muted beige top and dark jeans. Focused and precise, swinging a mallet
with determined energy.
Slide Context:
This image accompanies the Opening slide titled “Beyond _Just Try Harder_”. It sets the tone for the talk by
illustrating how reactive, people-blaming cultures make bugs harder to control. The talk is part of the Ways of Working
stage at LDX3, focused on systems that support high-quality software delivery.
