2) Grand Admiral Thrawn

Jokes about eerie contact lenses aside, if Ahsoka’s obsession with bringing the eyes of its animated characters to life as distressingly accurately as possible, it was all in service of one character: Thrawn. And it’s perhaps moderately forgivable that most of everyone else on this list so far kind of looked a bit weird considering that with Thrawn’s blood-red eyes, Ahsoka by and large nailed it.
Keeping the visual iris and pupils instead of Rebels instead of going for the blank-red look of the old EU depictions of the Chiss, Thrawn’s eyes balanced a fine line between the alien contrast of their coloration with still feeling human enough that Lars Mikkelsen could effectively emote. Artfully done, as the Grand Admiral might have once said.
