First sketch of the puppet, it was actually inspired by Madotsuki from Yume Nikki 

How the puppet was during early developpement 

Concept art of BIG FISH (this monster was the last scene I made for the game, he wasn't supposed to be there at all. I just had the idea at 3 am of a monster spawing in the background, then the next day it was finished)

The first thumbnail I made for the game
