Master Prompt:
Please create a high-quality, serialization-friendly illustration in the style of a "Cutaway Educational Picture Book" based on the [Theme].
This is not an ordinary illustration, nor is it merely a realistic structural diagram. Instead, it is a knowledge-based visual image that combines "cutaway display + internal structure explanation + functional zoning diagram + picture book texture + information labeling system." The image should allow viewers to simultaneously see the object's external form, internal structure, hierarchical relationships, functional logic, and key knowledge points. It should have both the explanatory feel of a diagram and the lively, engaging reading experience of a picture book.
[Input Theme]
Theme: [Fill in the theme here, e.g., heart / sunflower / giant dragon / library / volcano / whale / castle / submarine / magic tree]
[Automatic Understanding Rules]
Do not mechanically follow a single formula. Instead, automatically determine the most suitable visual expression based on the [Theme] and complete the following automatic enhancements:
1. Automatically determine which category the theme most closely resembles, such as human body, animal, plant, architectural space, mechanical device, vehicle, natural geography, fantasy setting, or other types.
2. Automatically determine the most suitable content focus for display, such as internal structure, functional zoning, operating principles, growth process, ecological relationships, hierarchical systems, spatial organization, or energy flow.
3. Automatically determine the most suitable audience comprehension level, overall leaning toward an expression style that is "readable for children + understandable for general science popularization."
4. If the theme is broad, automatically focus on the most representative core object or the typical form most suitable for cutaway display.
5. If the theme itself is not suited for strict "anatomical cutaway," alternative methods such as "partial cutaway / semi-transparent display / layered unfolding / cross-sectional explanation / internal space revelation" can be used to express it.
[Format and Composition]
Format ratio fixed at: 4:5 vertical.
The overall composition should reference the layout habits of high-quality cutaway science picture books or illustrative diagrams, suitable for creating a complete vertical knowledge illustration that fits modern vertical content platforms.
The main subject should be centered in the image and make full use of the vertical space to create stronger visual focus along the vertical axis. Through vertical extension, upper and lower layering, central main cutaway, and explanatory information distributed around the subject, both the external outline and internal structure should be clearly presented.
The overall composition should be clear, full, balanced, with a distinct main subject, natural information zoning, smooth visual reading path, and suitable for vertical screen viewing.
[Image Content Requirements]
The entire image should strive to incorporate the following features:
1. The themed object should be instantly recognizable, with a clear external outline.
2. Internal structures, internal spaces, or layered relationships should be clear and readable, with a sense of hierarchy and zoning.
3. Key areas should have clear functional meanings or knowledge explanatory value.
4. Appropriate small figures, small animals, small characters, or micro interactive scenes can be added to enhance fun and readability.
5. Elements such as arrows, numbering, short English labels, explanation boxes, partial magnification frames, and knowledge tips can be included as infographic components.
6. The information should be rich but not cluttered, allowing viewers to be attracted at first glance, understand the structure at second glance, and continue discovering details at third glance.
7. Optimize information layout based on the vertical format to avoid excessive horizontal stretching that could make the main subject feel scattered.
[Visual Style]
Overall, adopt a high-quality children's science picture book style that balances knowledge, approachability, and readability. The style should have the following characteristics:
- Clear, natural hand-drawn lines
- Outlines and shapes with a slight picture book feel
- Bright, gentle, clean color palette
- Clear structure without excessive engineering rigidity
- Rich details without clutter
- A sense of exploration, reading, and observational pleasure in the image
- Style positioned between "children's picture book illustration" and "explanatory diagram"
- Maintain picture book style, but overall visuals should be cleaner, more modern, and fresher
[Material and Texture Requirements]
Retain the picture book illustration quality, but do not add obvious paper material effects.
Avoid the following visual features:
- Paper texture
- Paper creases
- Printing noise
- Vintage distressed textures
- Central book page folds
- Page gutter seams
- Overly heavy paper grain
- Yellowed paper or old book texture
The overall image should resemble a "modern children's science picture book illustration draft" or "digitally drawn high-quality picture book explanatory page," rather than a scanned paper book page.
[Layout and Text]
The entire image should have a strong "picture book page + explanatory information panel" quality.
All text annotations should be written in English — concise, natural, and clear, using short English labels or brief explanatory phrases.
The annotation system should serve understanding, without overwhelming the page or stealing visual focus from the main subject.
Text and graphic explanatory elements should naturally integrate with the illustration to form a unified knowledge diagram layout.
[Color Suggestions]
Automatically match suitable primary and secondary colors based on the theme, but overall maintain the following tendencies:
- Bright, soft, easy to read
- Theme prominent, background clean
- Clear layers, not muddy or gray
- Suitable for children's cognition and general science reading
- Moderate use of accent colors to enhance vitality
[Prohibited Tendencies]
Do not create:
- Pure medical textbook-style realistic atlases
- Cold industrial blueprints
- Low-level toddler stick-figure drawings
- Ordinary poster illustrations without internal structure
- Images with only decorative appeal and lacking explanatory content
- Cluttered information overload
- Cyberpunk-style heavy light pollution visuals
- Obvious paper scan feel, page folds, or printing textures in an old book style effect
[Final Goal]
Make the entire image look like an exciting vertical explanatory page from a high-quality modern science picture book, or a cutaway knowledge illustration worth repeated observation. It should have both knowledge value and aesthetic appeal; both structural explanatory feel and engaging reading interest; suitable for children to view and appealing to adults as sophisticated, clear, and attractive. The overall image should fit vertical display formats, with focused visuals, clear information, unified style, and a sense of series continuity. All labels, titles, and annotations in the image must be written in English.
