This model is meant to recreate Emet-Selch as he appeared in Shadowbringers using the activator solusgalvus. This lora was not trained on his ascian outfit. As far as my testing goes it mixes very well with other style loras.
If you want to put him in other outfits you may need to put coat in the negatives.
I think epoch 3 matches his appearance most accurately but it is up to personal preference.
