Comlock,
Good to see your work here! The overall poses of your figures is pretty good!
I think that the areas with which you are experiencing the most difficulty are the lower legs and the arms of the right figure on your page of sketches.
Here are some examples of anatomy reference for legs which I also showed someone else today. I think that drawing and studying from books is the best way to study anatomy, but these are just a few examples of the kind of reference from which I think everyone should be drawing, in order to increase their knowledge and understanding of anatomy:

[left]Have you ever drawn from or studied Anatomical Reference? I think it is a great exercise to make copies of Anatomical Reference, either from books or the web, as a way of strengthening one’s knowledge, and ultimately one’s drawings from life. I was mentioning to someone else today that in the past, artists never drew from models until they had a good grounding of what to expect when looking at the live figure by first drawing from plaster casts or sculptures from antiquity. Sadly, that tradition is now lost for the most part, but with the web, it is possible to study in any way in which you please.
If you wish to do anatomical studies, and would be continuously updating your thread, feel free to create your own thread and call it Anatomy Thread of Comlock. This is the standard naming convention I like to keep for individual threads. You do not have to do this, as we have many threads to which you can post work, such as:
[center]Anatomy Studies of Skeleton / Bone / Muscle - TRADITIONAL OR DIGITAL
Master Copies - Post Your Copies From The Great Masters! 2D/3D D/T DRWG/PTG/SCULPTURE
Life Drawings - Post Your Life Drawings! From Class or Workshops
Hope to see some of your work on these threads as well! 
Cheers,
~Rebeccak
