Hello welcome!
Here I leave a small introduction of the LoRA:
After several tests I can say that something complex came out.
While it's understandable that hands are a big part of AI mistakes, this is one of the worst I've ever had (without help).
I sincerely recommend using a LORA for hands or simply use it as a tensioner adetailer to generate faces, this is the only thing I see useful. Of course, if you manage to master it, it will give you good results, but... did I win another Christmas star? :/
