The LoRA is intended to produce a woman with a cheek (or lip) retractor inserted for dental work.
V1 has frozen face it seems, though some things can be changed.
V2 is to fix the frozen face. I think it came out a little more crisp as well. It will give you a glitch from time to time, exposing the mask, but it's not often enough for me feel a need to redo it - I ended up redoing it O.o
V3 fixes previous masking issues and is probably the better version of them all. See the "About this version" for more details.
