Underwater Cave Merchant in Comic Book Style

A charismatic merchant in a vintage brass-diving suit runs a coral-studded shop inside a dim underwater cave. The scene is drawn in bold comic book style with thick black outlines, flat vibrant colors, and halftone shading. Shelves and stalls made of coral and driftwood overflow with treasures: glowing shells, enchanted trinkets, ancient coins, and map scrolls. Bioluminescent algae glow in electric blues and greens; sunbeams pierce the water from an opening in the cave ceiling, casting speckled light and bubbles everywhere. Curious sea creatures—angelfish, eels, and a friendly octopus—browse and linger. The merchant gestures dramatically as speech balloons float above: Fresh deep-sea finds! The composition uses dynamic angles, speed lines, and a sense of motion and adventure.
