some notes-Final Film

Today, I read a book named The Art of Monsters, INC. It was the second time I read this book. However, I got a lot of things new from this amazing book.
Pixar got a large number of concept art in their working.
concept art of the monster world;
concept art of Monstopolis;
concept of Monstropolis neighborhood streets;
concept of Harryhausen's sushi restaurant interior;
concept of Harryhausen's sushi restaurant exterior;
concept of Boo;
study of Sullivan and Mike
concept of background monsters;
etc.
A famous company like Disney, Pixar does a lot of work in their pre-production, I need do more work. Because I need long time and more references than them. I can't lose the concept art part of animation production, more concept ,better work.
