Underwater Hero: Comic-Book Horse in the Reef

A heroic horse swims underwater through a vibrant coral reef in a bold comic-book style. Thick black ink outlines, high-contrast shading with halftone dots, and dramatic action lines. The horse wears a vintage diving helmet and a flowing cape that mimics seaweed in the current. Bright tropical fish swirl around, sunbeams pierce the blue water, and bubbles trail behind as the hero surges forward. Include speech balloons with onomatopoeia like SPLASH! and WHOOSH! for a splash-page feel, plus dynamic perspective and vivid primary colors to pop against the underwater backdrop.
