Unable to replicate sample result

[k128]

When I run this line:
python hififace_inference.py --gpus 0 --model_config config/model.yaml --model_checkpoint_path hififace_opensouce_299999.ckpt --source_image_path assets\inference_samples\02_source.png --target_image_path assets\inference_samples\02_target.png --output_image_path assets\inference_samples\res22.png

the resulting image is:

What could be causing me to get a lower quality result than the published sample?
