Prompt: Putting "caucasian beauty", "nordic beauty", "blonde hair" or "white blonde hair" at the beginning of the prompt will increase the chance of generating a European or American girl.
Note: In flux 1.dev, there is already a similar concept, so this is not a strongly necessary LoRA. The role of this LoRA is to enhancing diversity, and of course it may be worse. Because the material is too dark, a small amount of errors are learned during training. Even when I tried to merge two epochs of LoRA, the improvement was limited. You can consider whether you can accept its imperfections, then decide whether to download. (flux v1.0)
Note: Basically, it is retrained after adding materials. V2.0 will look more like a blonde beauty, with a straighter nose and a lower error rate. Of course, v1.0 also has its advantages, and sometimes there are still some good pictures. If you don't like trouble, then choose v2.0! (flux v2.0)
