Question About Fine-Tuning

[Biggaoga]

Hello, thanks for your great work! And I tried to fine-tuning the pretrained model with my own head dataset with 200 different heads, but found it hard to get great geometry, here is one of the result, facial region exhibits artifact manifestations, and discontinuous features. Actually I just followed the toturial in README to preprocess the data and training. Do you have any suggestions about this?
