Use case: stylized-concept.
Asset type: themed raster icon collection.
Style: Collectible toy-like 3D science-fiction icons, rounded retro-futurist forms, smooth satin plastic, consistent three-quarter orthographic view, soft lighting from upper left, small ivory and teal details. Cheerful exploratory mood, strong silhouettes and restrained mechanical detail.
Color palette: main color [주조색], accent color [보조색]. Keep this palette consistent across the entire set while retaining recognizable natural object colors where necessary.
Subjects in exact row order:
Row 1: rocket ship; astronaut helmet; ringed planet; small cratered moon.
Row 2: artificial satellite; flying saucer; telescope; robot head.
Row 3: meteorite; five-point star; space capsule; antenna dish.
Row 4: solar panel module; fuel canister without writing; space rover; small crystalline alien plant.
Layout: exactly SIXTEEN distinct icons, one in each cell of a strict 4-column by 4-row square sheet. Read left to right across each row from top to bottom. Equal square cells with no visible grid. Center each complete icon in its own cell; keep its full silhouette within the central 65 percent of that cell, leaving generous transparent separation on every side. Same optical size and visual weight throughout. No overlaps, clipped shapes, empty cells, duplicate objects or bonus decorations. Background: genuinely transparent alpha everywhere outside the icons. No white matte, checkerboard pattern, colored tile backgrounds, circles, pedestals, cast shadows, floor, border, words, letters, labels, numerals, logos or watermark. Render only this icon collection, not a UI screen, photograph or presentation mockup. Output one square PNG sheet.
