You seem to be heavily focused on the silhouettes that the figure makes, which is a fine thing to practice, but I wonder if you also practice marking where the spine, ribcage, and hipbones are at other times? That can be very useful for learning WHY you're seeing the silhouette you are, and being able to draw more effectively from memory later.
I echo Kim's questions! :) Your gestures look really nice, but most people tend not to learn as much as they could from doing only silhouettes. I know I personally benefit from breaking bodies down anatomically, as they give me more flexibility to adjust the figures I draw without needing additional references.
