In Vikings, which has hands down the most obnoxious lighting it has ever been my misfortune to try to correct for. I'll probably do another set when my eyeballs recover.
As bb!Q'Orianka Kilcher in Princess Kaiulani. Only a few and not very polished, but I figure "small native Hawaiian girls in Victorian dress" is a PB niche that could use filling.
As bb!Gugu Mbatha-Raw in Belle (which you should see, it's pretty excellent); most of her expressions are wary and/or unimpressed, but to be fair, that's a reasonable reaction to being whisked away from home by a guy with too many teeth. I can't find anything on her age, I'm guessing 9-ish in these.
Turns out Beasts of the Southern Wild is a huge pain to icon. So many murkily lit interiors. So. Many. But I persevered, because Quvenzhané Wallis you guys.
