you need to make sure everything in the face is at the right angle
look at how certain features correspond to others, this is essential to any reference you work with, like how the ears line up with the eyes and nose, although this isnt the best example since her head is facing downwards, the ears are elevated somewhat. also how her neck lines up with her eye and part of her mouth.

also try to think in 3d whilst drawing, her head has a center line, and try to go from there when placing the features.
