You have a very interesting sense of style in your work, and handle the marker or sharpie well. That being said, I think you could work on leg anatomy and line of action a little more.
Going off of what Kaylee stated, you possess a wonderful and innate sense of shaping, but sometimes it gets a little out of hand in the anatomy of the legs. I love the way you go about shaping the face and upper torso in most of these, but when you stylize the legs, they tend to become too loose or floppy. You've got a good hand on shaping the rest of the body, so I've no doubt that you'll get past this minor issue.
