The training data pretty much starts in her late 30s, most is in her late 40s and early 50s, with some 60s in there.

"Young woman" or even "18yo woman" will bring her out at about 40, best of luck trying to get an 18yo Vorders. :D

In my defence, Flux is pretty poor at ages anyway - so, apologies if the LoRA is overtrained, but I'm going for optimum likeness over flexibility. Reducing the strength may help.
