"To clarify what is meant by proportions, we do not mean a prohibition on short characters or style choices. Characters that are canonically children or have features that make them appear underage would have to have appropriate proportion changes to be identified as an adult -"
"A good example of this is taking a short characters (say Judy Hopps) and showing what she looks like next to the younger rabbits. She is still shorter than many and when put next to a "bigger" version of herself as a child you can see the difference between them. "

They are still being vague about it. It's best to jump ship before the whole thing sinks. I'm already preparing everything for my new home and now that I've started I don't wish to stop. I'll keep my account here but mostly just so I can watch chaos unfold.
