/ic/ - Artwork/Critique

Keeping in mind that I was attempting to practice constructing the face and features and that I know next to nothing about value/tone, I have the following questions:

1. Some things seem 'off', like the left side of her jaw or the angle of her brow. Is there some trick to getting the alignment right or is it just a matter of getting good? Because I swear didn't notice until putting it down and coming back a little while later and now it's too late to fix certain things like the eyes and nose without basically re-drawing the whole thing.

2. Whatever you want to say about the drawing, it doesn't really look like the woman in the reference. I've had this problem before where people I draw look more like mannequins than the people I'm trying to draw. Any tips for trying to 'match' the source?
