I think I saw this man in a famous Chinese painting before. I think it was drawn when the Japanese were invading China in the second sino-japanese war. I forgot the name of the artist but I remember he was really famous. Please tell me the artist's name.
Rotoscope is when you trace over film to get believable animation instead of doing your own thing. He's saying he basically did this all from his head/based on observations of the world around him. Things like that fight between Phillip and the Dragon in Disneys' Sleeping Beauty were rotoscoped to an extent. It just gives you a heck of a lot more appreciation for all the hard work this guy puts to make his animation so believable it's hard to believe it wasn't traced. XD
