Whimsical Comic-style Illustration with a Playful Retro Sci-fi Vibe

Create a whimsical comic-style illustration with a playful retro sci-fi vibe. The setting is a lively intergalactic bazaar, bustling with floating vendor stalls and a variety of strange alien shoppers browsing unusual items. At the center, highlight a booth selling "Zero-Gravity Bubblegum," stacked with colorful boxes featuring neon-font labels that boast the slogan: "Chew It. Float Forever!" The gum package designs include quirky artwork, such as tiny astronauts encased in bubbles. Focus closely on one box adorned with a glowing holographic price tag that reads: “Now 500 Credits!” with the original price of “350 Credits” crossed out. Use a vivid palette of blues and luminous greens, with airbrush-style shading reminiscent of 1980s sci-fi comic art. The composition should exaggerate the chaotic humor of intergalactic consumer culture.
