1. To me, Disney is still the best at facial expressions. I would take clips from their movies and just study the facial acting in them. Grab a scrap piece of paper and a pencil, and start copying the faces frame by frame. You can do it from real life too, youtube has a lot of videos on facial acting. Point is, if you want to get better, draw as many of it as possible and just keep at it.
By the way, this guy is awesome at facial acting. I actually reference his face for some stuff.
