Gemini 2.5 Flash Nano Banana for one last time

Prompt: A captivating medium shot of a young woman with a warm smile, standing outdoors with a soft, out-of-focus background of trees. She has fair skin and long, wavy, caramel blonde hair with lighter highlights. Her gaze is directed downwards at her smartphone, which she holds in both hands as if texting or browsing. She is dressed in a cozy, oversized light blue hoodie. A light beige backpack, adorned with several small pins or patches, is slung over her left shoulder. Her accessories include a delicate silver-toned chain necklace with a small pendant and a beaded bracelet on her wrist. The overall aesthetic is casual, friendly, and captured in natural, diffused lighting.
