The Machine Girl Gangboss

If you have seen "The Machine girl" you will know why it's awesome. It's basically the story of a high school girl who's brother is the victim of bullying by a Yakuza boss's son. In seeking revenge for her brother the heroine loses her arm, which is later replaced by a mini-gatling gun weapon.
I am currently trying to learn how to paint (digitally) and so I figured that I would dedicate several posts to characters and stuff that I find awesome and painted in Photoshop of course. Since I need the practice I might as well have fun doing it. This is a sketch painting of the Kimura gang boss and his son from "The Machine girl".
