Early Sketch - Brazilian Folklore killing game

A while back I was hit with the idea of a Danganronpa style Killing game type of story featuring figures from the folklore of my home country of Brazil, so I thought it'd be fun to make some designs of the characters in more modern attire.

These characters are known as (from left to right): Saci-Perere, Iara, Boto Cor-de-Rosa, Mula sem Cabeca, and Kurupira.

I wanna develop these ideas a bit further when I have time.
