레트로 픽셀 우주 슈팅 게임 스프라이트

Create a clean sprite-sheet style asset image for a vertical retro pixel-art space shooter, on a plain white background with no grid and no labels. Show exactly 11 separate pixel-art spaceship and power-up sprites arranged in three rows, all with crisp black outlines, high-contrast shading, metallic panels, tiny vents, glowing cores, and 16-bit arcade detailing. Use a saturated sci-fi palette dominated by {argument name="main ship color" default="deep violet purple"}, teal/cyan, dark navy, black, gold/orange armor accents, and neon green energy lights.

Layout: top row contains exactly 3 large player/enemy ships: left is a small blue-white-and-gold triangular fighter with three bright cyan engine flames; center is the largest wide boss ship, symmetrical and heavily armored, purple and teal with multiple wing spikes, twin side cannons, gold trim, and a large glowing green hexagonal reactor in the middle; right is a tall vertical purple capital ship with pointed nose, side fins, teal panels, gold details, and a glowing green central reactor. Middle row contains exactly 4 medium enemy ships: a crescent-shaped teal and purple craft with two upward curved horns and a green cockpit glow; a compact rear-view purple winged fighter with side thrusters; a squat central gunship with teal cockpit dome, purple wings, gold barrels, and twin cannons; a broad purple bomber with swept wings, side engine pods, and a large dark central intake. Bottom row contains exactly 4 small collectible or module sprites: two square neon-green reactor power-up tiles with beveled purple/teal/gold frames, followed by two identical small cylindrical engine or booster pods with teal top caps, purple bodies, gold front panels, black exhausts, and tiny side fins.

Style constraints: production-ready pixel art, orthographic/top-down view, transparent-asset feel but rendered on white, sharp square pixels, no anti-aliased painterly look, no text, no watermark, no shadows beyond pixel-art contact shading, consistent scale hierarchy and spacing, like a polished mobile shoot’em-up tileset.
