this reminds me of my earliest days of doodling, if your looking for feedback the main issues here are anatomy, pose, technique. i would recommend picking up a variety of books that speak to your style and interests, especially graphite techniques.. Try rough sketching poses featureless poses, a massive amount of artists have developed arrested development because they are trying to draw for people or a culture or fandom (such a this one)
discovering your own sense of style then building from there will allow you to become so much more completed of an artist rather then drawing FOR people and there social idioms.

books "Anatomy for the Artist" and Burne Hogarth's "Dynamic Figure Drawing" are fabled books and will help you allot also "Pencil Drawing Techniques" has a wealth of information

hope this helps!

Thank you for the feed back and for the book suggestions.

Draw some circles. That'd help a lot. Also draw some spheres for shading.

That line going across the nose down to the mouth needs to not be there. As long as the nose is at the right place and angle it'll look fine without it.

Study hips.

That's all I got.

Thanks for the feed back.

yes thats excellent feed back, the bubble poses are usually the first evolutionary step for figure artists.
