NANA & Shinichi stories

Hi, from being soo emotional about NANA, I realized that I would like to continue Ai Yazawa's craft of NANA. Of course, I'm not as talented as her in artwork, but I am willing to continue her story from Ren's car crash. And as a side story: Shinichi Okazaki, an innocent, sad junior high student, who has a difficult past, wants to be free! What does it take to gain FREEDOM?
