Image Transformation to Minimal Vector Poster

A complex, structured prompt for Nano Banana Pro designed to transform an existing image into a clean, minimalist vector-style poster. It mandates geometric simplification, a restricted color palette (3–6 colors, no gradients), flat lighting, and the preservation of essential identity while removing all photorealistic details and textures. This prompt requires an input image to be transformed. Via YouMind OpenLab prompt library (MIT).
