Birthday Portrait with Foil Balloons

A prompt for Gemini Nano Banana Pro 2.0 to create a photorealistic, highly detailed 4K studio photograph of a smiling woman (based on a reference photo) in a navy-blue velvet dress, resting her hands on large reflective red foil balloons. The prompt allows customization of the balloon's age number and specifies elegant studio lighting and a dark charcoal-grey room setting. Via YouMind OpenLab prompt library (MIT).
