For the fur being so detailed as it is I can only imagine it was made using a particle system. You’d really only using curves if it was a more stylized, sparse type of fur. I can’t seem to find any tutorials pertaining to fur on a coat specifically, but I imagine any kind of realistic fur tutorial would be essentially the same thing. As for the cloth it’s a bit hard for me to say personally but if I used all 30 of my brain cells I’d probably say it’s a material/texture, as sculpting all of that seems like an absolute nightmare. But for my level of skill pretty much this entire character screams that haha.
