Heroine Expression Difference Grid Attempt

A Japanese prompt attempting to use Nano Banana Pro to generate a 16-panel grid showing different facial expressions (expression differences) of a heroine, based on a reference image. The prompt specifies that the top-left panel should be the original image, and the remaining 15 panels should show variations while maintaining the art style, similar to pseudo-reference functionality in older models.

Create expression differences for the heroine. Display them in a 16-panel screen. The top-left panel should be the original image as is. The remaining 15 panels should display variations of different expressions.
