Analysis: Brows slant downward. They're also bushy, which will make it easy for Anastasia to create a shape, because there's more hair to work with.

Prescription: Brush brows up and trim them; create an arch by tweezing where brows are heaviest, toward her nose. Make brows the same length with brow powder, applied with short, light strokes.
