I'm so glad that I stumbled onto this gem of a presentation by Disney. They go into incredible detail on how they designed their characters for Big Hero 6 and Frozen with lots of emphasis on design principles like shape and appeal. The process is definitely painstaking and requires lots and lots of disciplines to coordinate their efforts. It's definitely needed to get the best possible design that holds up against lots of animation. These guys show you how they designed some major and minor character from concept to finish and include steps like stress testing the character rig. They also talk about the pipelines between sculpted concept and usable asset. If you're into character development and look development, I highly recommend taking the time to watch this presentation all the way through. There is so much content to take in and the workflow that they demonstrated definitely feels straight forward and approachable.
