First time trying to draw a woman's face
please rate/comment

did this woman was in your head when you draw her or she was standing in front of you?

She was in my head

Thats pretty good from off the top of your head 8/10 i like the texture of your coloring

I agree, this isn't bad.

However, for a first time, I would practice first, like just google a pic or a portrait from someone in front of you.
This way you get an idea of how a realistic face is supposed to look. After you've got that down, make your own characters.

i agree with david
best if you draw with a picture first
and i think you might want to fix the chin
it's too flat

It's nice 9/10
ya the chin is a little off

Nagging about some proportion and pencil work things would be too much. You starting, learning and that's good. If you're serious you'll pick up things on your own, or someone will teach you. I'll just say that you should spent more time on hair, chin is objective thing (maybe u like girls with strong chin, what do I know... :P), and next time you do face shadows, take the mirror, position yourself close to some lamp and watch the shading on your face, then do the same on your drawing. Nature can't be wrong, and she's great teacher.
One thing that made me is a right eyebrow. Why the hell she has one eyebrow normal, and the other one is like ''Spock from Start Trek'' style?
