Milim Editorial Thumbnail
Create an authentic everyday slice-of-life editorial moment, not a product illustration, explainer, diagram, or hero scene.
Scale & Composition (Dramatic Scale & Negative Space)
- Scale Ratio: Milim MUST be very small (about 4–6% of total image height). Her tiny size creates a dramatic sense of scale against the surrounding world.
- World Ownership: The environment MUST occupy 88–92% of the frame, offering expansive, calm negative space.
- Flexible Positioning: Milim can be placed on the left, center, or right side depending on the focal point, framed by the surrounding atmosphere.
Guardrails
- Read
../marketing-tasks/MILIM.md before depicting Milim; it is the character authority. Keep her childlike (8-to-10-year-old chibi proportions), long-haired, unbound, and never give her twintails. Ensure she wears two yellow star hairpins in her bangs and her mascot outfit (black dragonoid hoodie, thigh-high socks with pink stripes, chunky sneakers).
- Use
gpt-image-2 or gemini-3.1-flash-image (nano-banana-2).
- Start every generation in
assets/workbench/generated/. Keep approved source art there; promote a production derivative to assets/generated/ and public/assets/ after review.
- Use 16:9 landscape (1600×900 WebP) for blog cards and inline editorial images.
- Do not use trees, roots, branches, canopies, forests, or tree-derived imagery as the primary subject.
- Never add readable text, letters, numbers, labels, logos, watermarks, UI, code, dashboards, charts, graphs, diagrams, or report pages.
Varied Emotions & Expressions
Milim should express authentic, relatable everyday slice-of-life emotions:
- Cozy / Content: Sipping hot cocoa, wrapped in a blanket, or sitting on a warm window bench.
- Curious / Focused: Examining a small object, inspecting paper stars, or reading a tiny booklet.
- Joyful / Bubbly: Smiling broadly, laughing under a rain umbrella, or watching steam rise from a fresh bakery tray.
- Sleepy / Relaxed: Rested against a bench, watching rain on a transit window, or listening to music.
Everyday Slice-of-Life Settings & Palettes
Vary the setting and color palette across every post. Do not default to the same night/starry scene:
- Vast Morning Bakery Conservatory: High sunlit glass arches, floating flour dust, towering bread racks, warm golden amber and cream palette.
- Rainy Bus Stop & Umbrella: Rain-streaked glass, reflections on wet pavement, cozy teal and indigo palette with bright yellow umbrella.
- Sunlit Greenhouse Plant Bench: Terracotta pots, green glass, morning mist, warm sage green and sunlit cream palette.
- Cozy Vinyl Record & Book Nook: Towering shelves of colorful paper sleeves, warm lamp light, wooden floor, warm brown and pastel lavender palette.
- Night Market Tea & Stationery Stall: Paper lanterns, awnings, steam, rich indigo and amber palette.
- Harbor Dock & Morning Sea: Portholes, wooden piers, calm water, crisp morning sky and seafoam blue palette.
