I personally don't like his design because I don't like horse villagers in general! I find them kind of unappealing. But he does get cool points for having most beautiful house interior out of them all! I didn't invite him on my island when I found him island hoping, but I understand his appeal! A very unique design!
i got him on my island as my first campsite villager. he's not someone i'd search for but i do like him. i'll probably let him go eventually, especially to someone who has him as a dreamie
i used to dislike the horse villager designs but i think they're better in New Horizons.
