I have already discovered why with some characters the hair goes wrong! Cropping images when the character has a complex hairstyle is not good for the AI, since it understands that they have different strange hairstyles, that's why if you are going to add images of girls with strange hairstyles to a dataset, make sure that all the images are visible. hairstyle in the images and that it is not cropped, compared to the model, as you intuit, suffers from this problem, I have also noticed that the images are out of focus and pixelated, this is because I trained it with old screenshots, another thing that you should avoid bad quality images, lately I'm learning from these errors thanks to the protocol I created, sorry for bringing you so many beta models, I hope to find time to make new models of those that are still in beta
