Description
A complex JSON prompt for the Google Gemini Nano Banana Pro model to generate an 8K hyper-realistic night portrait of a young man on a city balcony. Crucially, it includes detailed face preservation instructions, requiring the generated image to exactly match a reference face's features, hairstyle, and skin tone, while setting a festive, cinematic mood with warm golden lighting and bokeh.
