Automated generator-critique loops for evaluation may be really useful for creating your own style libraries, because its easy for an LLM-agent to evaluate how close an image is from a reference style or scene. So you end up with a series of base prompts, and now can replicate that style across a whole franchise of stories. Most people still do it with reference images, and it doesn't really create very stable results. If you do need some help with bounding boxes for nano-banana, feel free to send me a message!
