This is my Flux version of a "mature-woman" lora that helps produce female characters of approximately 40-60ish age. Flux and most checkpoints seem to have a lot of trouble with this particular age group. Use the terms "mature", and/or "middle-aged" in your positive prompts. Don't forget to check out the SDXL version here: https://civitai.com/models/1423376/mature-women-sdxl
