I'm hoping they let you pick the size of your characters, just like a Mii on the Wii. They just look so different, they have the same heads but these skinny anorexic bodies XD
In all the previous Animal Crossing games, your character was still a "child" right? receiving letters from your mom and stuff. Maybe they look that way cause now they're "grown up?"
It'll take some time getting used to for me at least.
