Nanobanana Prompt Engineering Workflow

① Create a "[character 1]" and a "[character 2]" wearing ice skates, and the background location. Normal chat-based input is also OK. Whether you generate it all at once or separately, the process is the same.

② Perform annotation on the image.
This is the most troublesome part, so I made it a tool.
Based on the file name, I create a prompt that organizes "which part of which image to reference."
(Pose / BG / Face / Clothing, etc.)

③ Add supplementary information such as composition and color scheme for the final generation.
