I am somewhat surprised at how bad these tools are at generating hands and feet. Is it just a matter of not having enough images to ingest? The faces often look very good and they also have symmetric complexity and individual elements that come in a specific quantity (2 eyes, etc). Lower quality models do generate fly-like multi eye faces, but newer ones are so much more precise!
