Prompt
A vertical 2:3 composition that reads as a Memphis-style night sky rendered as a vector illustration with a deep, near-black purple field occupying the full background and framing the scene. Five larger anchor motifs occupy the lower-left, center-left, center, center-right, and upper-right thirds, while dozens of smaller geometric elements — semicircles, squiggles, triangles, cylinders and confetti dots — are distributed across the left and right thirds and near the top third to suggest drifting constellations. The central area remains visually active with a mid-size cluster of shapes that fills roughly the middle third without touching the edges, leaving generous negative space in the lower third for typographic placement. Shapes use flat pastel fills of soft pink, pale blue, buttery yellow and mint with occasional thin black outlines and subtle inner drop glows that suggest gentle luminescence against the dark field. Lighting is implied by soft rim glows and faint radial vignetting that deepens toward the corners to enhance depth and contrast. Materials read as clean flat vector shapes with crisp edges, slight paper-like texture on the background, and no photographic grain, intended for poster printing at a 2:3 vertical crop.
