Visible crew/equipment: When one of the guards cries "Destroy it!" watch to the left of Karga and you'll see a crew member in jeans hiding behind a wall. This was later edited out on Disney+. (00:18:54)
Visible crew/equipment: The kid actors in the school scene several times break fourth wall looking very distinctly at the camera. The kid directly behind the Child does it right away as Carl Weathers brings it there, and when Gina Carano is heading out there's a kid in the foreground who steals a worried peek at the camera, impossible not to notice.

Chosen answer: They could be just like wrinkles from age, like the elderly Togruta in the Zygerrian slaver arc in The Clone Wars series, as Ahsoka is considerably older than her animated appearances. I think there is probably a character design/stylisation aspect to it as well - the other Togruta we've seen in live action, Shaak Ti, has four segments or folds in her lekku that were not visible in her Clone Wars appearances, so it would seem the character design in Clone Wars and Rebels reduces such features.
