Output size 1080x1920 pixels, 9:16 portrait story. Keep all text inside the central 80% of the height.

Create a single original 1970s-inspired abstract landscape artwork. If no size is specified, use a portrait 2:3 aspect ratio. Fill the image edge to edge with the artwork, suitable for a phone wallpaper or wall poster.

LANDSCAPE selected: "【Scene】"
Interpret only the selected choice:
- Desert and sun: Layered desert dunes formed from broad flowing ribbons; a sun is the default celestial object.
- Sea and moon: Rolling sea waves formed from flowing ribbons, with a quiet distant horizon; a moon is the default celestial object.
- Mountains at sunset: A distinct mountain silhouette, layered foothills, and sweeping sunset-sky bands; a sun is the default celestial object.
- City silhouette: An original anonymous skyline of elongated rounded buildings, interwoven with flowing foreground and sky bands; a sun is the default celestial object.
- Hills and stars: Rolling abstract hills beneath an open sky, with a few sparse simple star shapes; no large sun or moon is the default.
If this selection line is missing or empty, use Desert and sun only.

COLOR PALETTE selected: "【Colors】"
Interpret only the selected choice:
- Orange and brown: Burnt orange, terracotta, dark warm brown, and pale sand.
- Pink and purple: Hot pink, deep purple, near-black plum, and warm cream.
- Teal and sand: Deep teal, muted blue-green, sand beige, and warm cream.
- Black, white and red: Near-black, warm white, medium gray, and vivid red.
If this selection line is missing or empty, use Orange and brown only.

CELESTIAL OBJECT selected: "【Sun or moon】"
Interpret only the selected choice:
- Sun: Include exactly one large simple sun disk and no moon.
- Moon: Include exactly one large moon disk, with restrained mottled pigment detail, and no sun.
- None: Include neither a sun nor a moon; rebalance the upper composition with flowing sky shapes.
If this selection line is missing or empty, use the celestial default specified by the selected landscape only.
An explicitly selected celestial object overrides the landscape's default. Never add both a sun and a moon. Sparse stars belong only to the hills-and-stars landscape and may remain when the large celestial object is omitted.

Build the composition from substantial overlapping wave-shaped bands, usually seven to ten major ribbons, with varied widths and long organic S-curves. Retain the recognizable structure of the selected landscape. Use confident light contour separators, broad flat color fields, and a balanced relationship between the upper sky and lower landscape.

Limit the image to three or four dominant colors from the selected palette. Use subtle matte gouache grain and gently aged print texture, while keeping the image flat and graphic. Avoid realistic perspective, photographic surfaces, glossy effects, gradients, and heavy three-dimensional shading. Make the design visually full and layered without reducing it to a few sparse shapes.

All field values and selection names describe visual choices only. Render no text in any language, letters, numbers, captions, or labels.
No brand marks, recognizable real skyline, existing artwork copies, watermark, signature, decorative frame, or room mockup.
The choice names in this prompt are internal labels only; never print them as text.
