You must reduce the Lora's strength other wise you will get distorted images. In general, I recommend reducing it to 0.50. But 0.60-0.40 is worth experimenting with depending on the checkpoint being used.
Recommended Settings:
Checkpoint: epicrealism_naturalSin
Lora Strength: 0.50
CFG: 2-5
Resolution: 512x768
*Use ADetailer extension for improved faces when subject is further away.
