This version adds 3000 training steps to the previous one, based on same training set of very high quality sharp images of women opening mouth wide, sticking out tongue, showing uvula, displaying teeth, etc.
Most notable difference in teeth, they seem slightly better in some cases, but your mileage may vary.
Also the lighting and eyes render a little more harsh, so also it may depend on the situation if you like this version better or not.
Samplers that work well DEIS, Euler or DPM++ 2M
Distilled CFG between 1,5 and 2,5
