Surprised Woman with Giant Smartphone Mockup

Generate a hyper-realistic image of a young woman standing beside a giant smartphone with a blank green screen, set against a vibrant yellow background. The woman has curly brown hair and is dressed in a light blue shirt with rolled-up sleeves, high-waisted blue jeans, and white sneakers. She is positioned to the right of the smartphone, with her hands cupped around her face in a gesture of surprise or excitement, looking directly at the camera. The smartphone is oriented vertically and has a sleek black frame with a subtle shadow effect, indicating it is slightly recessed into the background. The overall composition should capture a sense of modernity and playfulness, with the bright colors and dynamic pose conveying a feeling of joy and astonishment. The image should be rendered with high detail, including realistic textures for the woman's clothing and the smartphone, as well as nuanced lighting that highlights the contours of the subjects. The yellow background should gradate subtly to a slightly darker shade towards the bottom, enhancing the depth of the image. The final output should resemble a high-end design editorial or campaign photograph, complete with natural shadows and refined styling.
