After meeting with Kongdech and Thum there are some general comments for all the work.
For everyone working on the zombie world scenes, Kongdech feels the design will be stronger if we come up with Zombie world rules/logic. Why is there a zombie world? How do they live? Where do they get their clothes from? What are their clothes made of? What are zombie world physics like? Do you go down to the human world and up to hell? What kind of person goes to the zombie world?
You have the freedom to come up with your own rules and ideas. Try to sell them to the director.
Below is a copy of the directors idea for the connection between the two worlds. Notice how up and down are opposite from each world.
