I always noticed that Tempest has no dark pupils compared to the other ponies. One might think that was a metaphor for her being "dead inside", but if that was the case then at the end of the film her eyes should have darkened again. I actually wonder if it was in her original concept art with a side profile of her face only showing her scar, that the scarred eye was supposed to be "dead" and they accidentally drew both eyes that way, and they ended up deciding making one pupil dark and the other light was too off-putting so they left it.And I think the animation was far "kinder" to Tempest Shadow than it was the Mane Six. Every one of Twilight's close-ups made me cringe.This is great work though.
