IMPORTANT!
Instructions:
Lora is made in such a way as not to change the overall concept of the picture too much. She is a kind of amplifier and expander of the boundaries of the model.
For a greater effect, identify the age with words (read this article). Feel free to use the weight for these words, for example (old woman:1.1) or (old woman:1.6).
Lora working weight is -3 / 3. Within these limits, she will not distort the picture for you.
Work Realism and Anime models.

P. S. No, none of the images were upscaled or hiresfixed.
