atm, id say that you have consistency issues with face structure and pretty much the head as a whole. when you draw them, it appears as if the face is slanted or skewed to a direction. here's an example:
im assuming that the face is supposed to follow the body, in a sort of straight way. however, in this drawing, its as if someone is pulled on her cheek for years and it caused her face to be sorta morphed. i made an edit which may or may not help you get an understanding of what im trying to talk about.
i recommend that you practice your heads and faces so that this sort of thing can be prevented in some way.
