This might be an uncharitable way to put it, but she looks like a potato, or perhaps several. It might benefit you to find a different approach to skin texture, and the facial features seem very two-dimensional while the piece as a whole seems to be striving for three. The shape of the eyes strikes me as off, but that could just be me. Overall the anatomy seems to be just a series of oblongs, so in future perhaps refine the shapes more. Best to you in future.

Needs more work here. Um she did have well breasts. Those are well hidden. Nice angle though. Try again and work on the face and neck. The face is flat for one thing and the neck is way too long. Not trying to be hard to get along with, but these are the faults I see. Her shoulders are too um mounded. Not sure if that is the technique thing you're after...
