You captured the figure quite well here, incorporating many different style techniques - stippling in the top right-hand corner, creasing in the top left - and it serves well.
The bottom-right drawing is my favourite. I love the interpretation of her figure, and you angled it just right.
My suggestion for improvement (There's always room) would be to more effectively shade the stippling. With stippling, it's easy to create different values with the pen, which is basically making the marks closer together and less defined for shadows.

[link] is an example of effective stippling. You can see the shading, how the marks get darker and closer together for shading, and farther apart for lighter sections.

This is quite a nice piece all in all!
