Beachfront Fortress in Comic Book Style

A tropical beach at golden hour with turquoise waves lapping pale sand. In the distance, a massive stone fortress rises from the waterline, its crenellated towers and seawall jutting over the surf. Rendered in bold comic-book style with crisp black ink outlines, flat bright colors, and a halftone texture. A superhero in a vivid costume stands atop the fortress ramparts, cape fluttering, scanning the horizon. Foreground shows footprints in the sand and a half-buried seashell. Use a dynamic low-angle perspective from the beach, dramatic speed lines, and panel-like borders. Include speech bubbles or caption boxes with onomatopoeia like "KRA-BOOM!" and "SWOOSH!" to amplify action. The mood is adventurous and heroic, with high-contrast lighting and a palette of warm oranges, electric blues, and bold reds.
