Retro Pixel Space Shooter Sprites

Create a clean, sprite-style image for a vertical, retro pixel-art space shooter game. The background is pure white, without grids or tags. Showcase 11 individual pixel art spaceship and prop sprites, arranged in three rows, all featuring sharp black outlines, high-contrast shadows, metallic panels, tiny vents, glowing cores, and 16-bit arcade details. Use a saturated sci-fi color scheme, with the main color being {argument name="main ship color" default="Deep violet"} The layout is accented with cyan/blue-green, deep navy blue, black, and gold/orange armor, as well as neon green energy lights. The top row contains three large player/enemy ships: on the left is a small, triangular fighter in blue, white, and gold, with three bright cyan engine flames; in the middle is the largest wide-body boss ship, symmetrical and heavily armored, with alternating purple and cyan colors, multiple wingtips, side cannons, gold decorations, and a large, glowing green hexagonal reactor in the center; on the right is a tall, vertical purple capital ship with a pointed nose, side fins, cyan panels, gold details, and a glowing green central reactor. The middle row contains four medium-sized enemy ships: a crescent-shaped cyan-purple aircraft with two upward-curving corners and a green cockpit glow; a compact, rear-viewing purple wing-shaped fighter with side thrusters; a short, stout central gunship with a cyan cockpit dome, purple wings, gold cannons, and twin-mounted cannons; and a large purple bomber with swept wings, side engine nacelles, and a large, dark central air intake. The bottom row contains four small collectible item or module sprites: two square neon green reactor blocks with beveled purple/cyan/gold borders; followed by two identical cylindrical engine or booster bays with cyan top covers, purple bodies, gold front panels, black exhaust vents, and tiny side fins. Style restrictions: Production-grade pixel art, orthogonal/top-down perspective, with a transparent texture but rendered on a white background, crisp square pixels, no anti-aliasing, no text, no watermarks, no shadows other than pixel art contact shadows, consistent proportions, hierarchy, and spacing, presenting a refined mobile shooter atlas effect.
