Since the video didn’t extrapolate all of them, I’mma repost them here (from http://oddworldlibrary.net/archives/scriptures/diaries/Abe%27s_Exoddus/Paint—By_The_Numbers ):

Guiding the paint artists in their pursuit of perfection is the ‘Oddworld Signature,’ a series of six artistic commandments created by production designer Farzad Varahramyan and director Lorne Lanning.

All images must:
1) Be realistic.
2) Have solidity.
3) Be original.
4) Be cool.
5) Evoke emotion.
6) Look ALIVE!
