Coppia di supereroi contro un supercattivo in stile mezzatinta

Photorealistic CMYK halftone illustration: A superhero couple, one with heterochromia, in a dynamic battle against a supervillain. Smooth shading, high contrast, and a vintage newspaper/comic book reprographic effect, with sharp, intricate dot details and no solid fills. Golden ratio composition, with 15% negative space above heads and 21% below feet (head-to-toe shot). Dramatic, high-key lighting emphasizing the dotted texture. A color-graded, hand-signed calligraphy signature 'Bic Revelation' in the bottom-left corner. 8K resolution.
