I'll start with this one since you did a pretty darn good job on the eyes.
Especially the iris and pupil are quite captivating in this piece. I love the fact that you added the reflection of the eyelashes on the iris.
The nose and the mouth could use some work but I know how hard those are so I wont give you crap about it. The way I trained myself is to draw a "wireframe" like you would see in 3d programs. That gave me a pretty good idea on what to shade and what not. Other than that the good-old rule of practice makes perfect, of course ;]
I'd cut out the right eye (her left) and save it, you did a very good job on it!
