>For every person who gets to make creative decision, there are hundreds upon hundreds of people whose sole purpose is slavish adherence to those decisions. Miyazaki gets to design his beautiful characters - but the task of getting those characters to screen must be carried out by massive team of illustrators for whom "creative liberty" is a liability to their career.

This is vastly oversimplifying and is misleading. Key animators have a highly creative role. The small decisions in the movements, the timings, the shapes, even scene layouts (Miyazaki didn't draw every layout in The Boy and the Heron), are creative decisions that Miyazaki handpicked his staff on the basis of. Miyazaki conceived of the opening scene [0] in that film with Shinya Ohira as the animator in mind [1]. Even in his early films, when he was known to exert more control, animator Yoshinori Kanada's signature style is evident in the movements and effects [2].
