I assumed that's why we haven't seen any Star Wars face characters yet. A face character is easier if they're based off an animated character (because there's lenience) or someone like Captain Jack Sparrow who has a lot of makeup and stuff, but I can imagine characters like Luke, Leia, Han, Finn, and Rey being hard to pull off. That's why we're mostly getting characters like Vader, Chewbacca, and Ren.
