For the characters I generated the bodies with MakeHuman in Blender to get a starting point, then modeled the heads/eyes/mouths myself (which is why it looks so off) and attached it at the neck. pic related is clear how fucked up the neck is
For the hair/skin materials I followed tutorials to get something that looked reasonable.
For the other models like the mailbox, cardboard, glasses, fence/houses/grass/bushes I modeled them myself freehand.
