'The Art of Ratatouille'

"When you do a sculpt of a character, you are often working from concept drawings, or maybe just one drawing. A drawing will likely have 2D 'Cheats'-distortions or inconsistencies that can give it life and energy. The cheats look great, but may only work on paper. So the challenge is to take an inspiring 2D design that shows a character from one angle and translate that into a great 3D design that is symmetrical enough to look consistent across multiple angles. Sometimes you discover a very different design from what you would have expected, and you can surprise yourself and the director. But hopefully, even though the solutions you come up with may result in some noticeable changes, the sculpt with retain the essential look and feel of the concept drawing. Now, when you turn the sculpt around, you can see what he or she looks like from the side, or from the top. You'll see things about the character that you had never seen before."
