I highly recommend using the ADetailer extension for better faces and eyes.
For v2, I merged v1 with some NoobAI models, @GarejiSama's AdAstra and @Manityro's Vermilion, making v2 much more compatible with NoobAI based LoRAs.

LustrousMix v2 generations are more colorful than v1's, with more contrast and sharpness. There is a slight art style change as well, with more mature faces.
