Commenting on the makeup, she looks pretty ethereal in character and not too heavy makeup wise.
I'd go for a more natural, dewy look more than anything. Use light browns and pinkish (not overly pink) shades for the eyes. I'd also use highlighter to brighten the face
. I attached a video about how to apply it, and what exactly it does. Go simple on blush or bronzer, not much would be needed.
As for the lips, I'd avoid lipstick in general. I'd go for a light colored stain with a simple gloss, or lip balm over top. It'll give it a little bit of color without looking cheap or overdone.
