About This Prompt

A structured JSON prompt template for Nano Banana Pro, designed to generate a dynamic, modern comic book poster illustration (16:9 aspect ratio) with a collage of comic panels, halftone effects, and dramatic lighting. It includes placeholders for the main character, title, and specific panel content, and requires strict identity preservation from a reference image.
