ملصق فضاء ثلاثي الأبعاد بروح المستقبل الرجعي

A vibrantly colorful retro-futurism vertical poster featuring a chunky 3D cartoon rocket ship in [glossy candy red] with bright yellow fins and a round porthole window, launching upward while trailing a thick swirling rainbow exhaust cloud in [electric pink, cyan, lime green, and orange]. Surrounding the rocket are oversized 3D planets in vivid hues: a giant striped Jupiter in warm orange and cream, a ringed Saturn in pastel lilac with a glowing gold ring, and a tiny Earth in vivid turquoise and emerald. A floating 3D astronaut helmet in chrome displays a rainbow reflection on its visor. The deep cobalt blue gradient background shifts from royal blue at the top to warm violet at the bottom, scattered with dozens of glossy 3D stars, sparkle symbols, and comet trails. Bold, chunky rounded 3D typography at the top reads "[SHOOT FOR THE STARS]" in massive gradient letters shifting from hot pink to electric yellow, accompanied by a smaller bouncy subtitle reading "[Dream big · Launch bigger]". Ultra-vivid saturated colors, premium 3D illustration finish, dynamic vertical composition.
