Prompt
A cephalopod anatomy figure: whole octopus in ventral view with arms numbered, mantle cutaway exposing gills, ink sac and digestive gland, a chromatophore skin inset, and a sucker magnification. Label "MANTLE", "GILL", "INK SAC", "CHROMATOPHORES", "SUCKER". Title: "THE EIGHT-ARMED ENIGMA".. Workflow direction: Create one publication-quality science-communication illustration in a single generation. It must demonstrate both visual craft and explanatory power: a compelling central subject, a clear reading order, multiple meaningful layers of information, and a polished editorial composition that still reads at thumbnail size.
Follow the user's requested entities, relationships, sequence, viewpoint, audience, and quoted text exactly. Pick the figure grammar that best serves the topic and state it through the rendering itself: anatomy or specimen plate, cutaway or cross-section, molecular or signaling mechanism, step-by-step process or workflow, side-by-side comparison, system or network architecture, chart or plot, instrument diagram, or narrative scene. Match the rendering technique to that grammar — flat clean vector for flows and architecture, dimensional molecular rendering for micro structures, semi-realistic tissue or material rendering for cutaways, cinematic depth only for scenes — instead of forcing every topic into one house style.
Default canvas is a clean white or near-white field like a journal figure: no decorative frame, plate border, aged paper texture, or faux page furniture unless the user explicitly asks for them. Label the figure the way a journal would: direct horizontal text joined to its structure by a thin non-crossing leader line. Switch to numbered markers with a compact key only when the subject is too dense for direct labels, and include a legend only when color or symbols encode meaning. One short title, 4–8 essential labels, purposeful arrows for real movement, sequence, reaction, or causal flow with consistent arrow grammar, and at most one magnified inset that adds genuine understanding.
Render requested English or Chinese text as sharp, horizontal, high-contrast, correctly spelled text; never paraphrase quoted labels or leak prompt instructions into the artwork. Reserve a generous 10–15% outer safe area on all four sides; every title, label, leader line, legend and inset must be fully visible inside that safe area, never touching or crossing the canvas edge. Prefer fewer complete labels over cropped or microscopic copy.
Scientific accuracy outranks decoration. Preserve topology, orientation, relative position, sequence, direction and scale cues; never invent anatomy, structures, measurements, provenance, causal relationships or pseudo-data. When literal scale cannot fit, visibly signal a schematic or not-to-scale treatment. The result must be self-contained and credible as a figure a researcher could paste into a manuscript, thesis, grant, poster, textbook, classroom explainer, or public-science article.
Style-specific direction:
Style: authoritative field-guide zoology figure — precise, evenly weighted linework with restrained color modeling and clean contemporary annotation on a white field. Shift to museum natural-history art with fine stipple and ink and restrained watercolor only when the user asks for a classic or archival treatment.
Subject conventions: preserve species-defining morphology, posture, body proportions, articulation, and the requested anatomical orientation.
Composition: one primary specimen plus a second scientifically useful view, functional anatomy inset, or scale comparison; keep habitat context secondary and explanatory rather than cinematic.
Color: restrained specimen-true hues with subtle tonal modeling and high edge clarity.
Label convention: direct labels point to visible landmarks without crossing the animal silhouette unnecessarily.
Avoid: dramatic wildlife scenery, anthropomorphic expression, unrelated species, and invented structures.. Avoid: invented facts, misl
