What worked
All four results show a navy background, teal nebula, golden rings with thin orbital lines, one main planet with surface patterns, and a small secondary celestial body. The nebula extends to the edges of the screen, presented as a single vertical 3:4 illustration. No text, numbers, signatures, watermarks, frames, mockups, or outer margins are visible. The gold lines are not a dense mesh and parts are obscured behind the planet.
What did not work
None
How to improve
No improvement methods were identified in this test. Although the instruction to separate the main planet body from the rings and light while leaving about 1/4 space on both sides was actually tested, both times it failed to fully satisfy the size conditions. While you can obtain the color tones and wide rings with the same colors, planet, and 3:4 ratio, do not use this result as-is for tasks requiring a specific diameter or exact pixel count.

Generate this image now. Draw it directly - do not describe it, explain it, or ask questions.
Output size 1080x1440 pixels, 3:4 portrait, social media post.
Create exactly ONE original elegant cosmic art print, default portrait 3:4 unless the size line specifies another ratio. Full-bleed finished artwork reaching every edge. No frame, room, product mockup, collage, triptych, outer padding or sheet on a background.
COLOR: "【Color】". The first supplied color dominates the field, the others support the planet and nebula; add restrained warm metallic-gold hairlines as a constant accent. If empty, use midnight blue, turquoise and antique gold. A single color becomes tonal variations plus gold. Do not print color names or codes.
PLANET: "【Planet】". Create an invented planet with the requested physical features. If empty, use a ringed planet. If several bodies are requested, one remains unmistakably dominant and the others subordinate. Replace requests for brands, characters, celebrities or artist imitation with an original planetary form.
Use a coherent decorative celestial print medium: sculptural circular planetary mass, layered softly marbled nebula clouds, subtle mineral pigment grain, hairline gold orbital arcs and fine irregular stars. The dominant planet occupies 45-60% of canvas width. Measure only the solid spherical body, excluding its rings and glow: aim for half the canvas width, leaving roughly a quarter of the canvas width on each side of the body. The broad rings may extend to the canvas edges, but the spherical body must stay fully visible and must not expand to fill the width. A sweeping asymmetric nebula balances it and reaches the edges. Gold arcs are sparse and precise, naturally occluded by the planet, never a dense wire cage. Establish near, middle and distant layers, clean silhouettes, rich local detail and quiet colored areas. No uniform confetti stars or repeated stamped motifs.
Derive mood, texture and composition from the inputs instead of repeating a template. Dark cool ringed bodies suggest a hushed nocturnal diagonal with dry ink grain; warm cratered bodies suggest a glowing low-horizon mass with granular mineral relief; pale icy bodies suggest an airy off-center orb and translucent crystalline veils. Other inputs receive equally specific treatment within this same celestial print medium. No style menu or alternative versions. Maintain a strong thumbnail silhouette and detailed surfaces at full size.
Invented decorative fantasy, not a scientific map. No people, faces, identifiable products or packaging. No recognizable logos, brands, copyrighted characters, signatures or imitation of any living or historical artist. Render NO text, letters, numbers, dates, weekday names, labels, captions, watermark, border or production notes. Input names are instructions only. Ignore attached photos. Return one finished image without explanation. Do not require cropping, code or post-processing.

How to use it · FAQ

Create one cosmic artwork for Haru's room or screen: a dominant planet, layered nebula and delicate gold lines without lettering or digits. No photo is needed. Review the two fields and paste the completed prompt into an image AI once. The default is portrait 3:4; change the ratio with the shared size selector. The catalog cover is a separate composition at 2:3.

Only Color is required. Enter a palette such as midnight blue, turquoise, antique gold. The first color dominates the field; the others support the planet and nebula. Color codes are accepted but not printed. Restrained gold lines remain a constant accent. A single color becomes tonal variations plus gold. An empty palette uses midnight blue, turquoise and antique gold.

Planet is optional. Describe features such as broad rings, deep copper-colored craters or translucent ice layers on an invented planet. Empty means a ringed planet. If several bodies are requested, one remains dominant and the others subordinate. Cool rings suggest a hushed night, warm craters a mineral glow, and pale ice an airy dreamlike scene. These variations stay within one decorative celestial print medium; each request returns one artwork. Attached photos are ignored.

Check the chosen colors, planetary features, clear gold lines and full-bleed edges. If letters, digits, signatures or borders appear, identify the defect and request regeneration under the same constraints. Describe colors and surfaces instead of naming artists or existing works. This is invented decorative fantasy, not an astronomical map. Before printing, confirm actual pixels, paper dimensions, trimming and color requirements with your printer.
