Two detailed prompt variations for Nano Banana 2, designed to transform an input character image into a photorealistic advertisement poster displayed in a busy Japanese subway passageway. The first variation includes 'Portfolio Expression' for dynamic cropping and varied poses/expressions, while the second maintains the original character's appearance more strictly.
