Hi Artysm,
Looks like you've been putting in some regular hours. I think all of the figures read quite clearly overall which is a good sign. The one thing that stands out to me is the dominant curved or ovoid nature of all of the figures. which misses out on some of the dynamism combinations of curves and straights. I would look at some of the figure drawings by Charles Bargue or even some sketched portraits by Ingres, as well as some of Michelangelo's figures. All of these draftsmen show examples of how we can include flowing curves alongside harder straight lines to have a more dynamic figure.
keep it up and enjoy the process.
