strength 0.6-0.8, hiresfix or img2img for best results(it's works for every LoRa).

if you get bad results - try https://civitai.com/models/4669/corneos-7th-heaven-mix this checkpoint and write in prompt position(like "front view, face"), because dataset contained not only front-face.

i focus on true anime style models for fanarts or fanmanga creation, if you want artstation ultra quality arts style this isn't your choise.

Train models isn't easy, crypto donations on some coffee are welcome:
