Unfortunately, although Lora can be used to expand the model’s applicability, it’s more about emphasizing certain aspects rather than enhancing its capabilities. Achieving perfect piano details is akin to having a perfect hand—it exceeds the current model’s capacity. Claims that Lora can fix hand details are merely beautiful fantasies. There’s one exception: if I significantly reduce the training set, perhaps Lora could ensure perfect piano keys at the cost of only generating fixed-style images, but that wouldn’t be desirable.
