Satoru is an original I have been working on slowly for a fairly long time. The art style in his design interprets a significant influence from Japanese Manga and Anime into a 3D space with physically realistic shading as opposed to toon shading.
I've had Satoru both in the back of my head and hidden away in my secret vaults for a few years now, and have been taking it very slow working on him, starting over numerous times in the process. My intention with this model is to eventually use him and a few other original characters in a game after optimizing him (most likely an RPG or possibly a fighting game).
