To be honest I don't care much about the species generally speaking, I'll always find villagers I really like in each one, but just going off shape alone and not personality or appearance here is mine
I added an F tier because my D tier was way bigger than I thought it'd be... I never though I was this negative about villager types, but it really depends on the specific villager, not the species! and it didn't help that most of the specific villagers they used are some of my least favorites of the species.
C tier is my "meh" tier, so that's where most of em went. They're alright, but I somewhat prefer the others. Though I prefer looking at the character themselves rather than just the species :>
It was fun to make, although it made me realized that there's many species I don't know too much about haha... I'm sure if I had some villagers of my C/D species it would go up in rank. Maybe not D. Haha
