It's the little things.

[EduartBoudewijn]

Definitely the smaller details of a character carrying over into their new form; this can include small things like (body) jewelry or makeup, but also other things, like a character's hair color carrying over (either standing out from their new fur color, or blending into it); or their body size carrying over (So a larger individual turns into a larger specimen and a smaller individual turns into a smaller one).
