Since I've more or less learned how to make LoRAs, I've collected a bunch of Animal Crossing art to make them out of. This is the one for Digby, Isabelle's brother and one of the 3 premier femboys in the series.
Trained on 238 images from e6 for around 6000 steps, I used combined e6 and auto tags pruned them as best I could so you shouldn't have to write in his character name, but there are others that should help:
general tags:
anthro, brown hair, brown fur, bright pupils
nsfw tags:
girly, otoko no ko, backsack
canon outfit:
suit, red jacket, red pants, necktie
isabelle outfit:
crossdressing, green vest, gringham, short sleeves, green skirt
negative tags:
1girl, female, girly, heart
-girly if you don't want femboy dig, -heart because sometimes it likes to put random hearts in the bg
