Nicer job on your lines of action and the livelier lines of action and rhythm and balance in your poses thus far, but they all don't seem to lighter enough yet, yet how would you like to go for 2.5 hours of 22 second poses? The reason why is because, it can make your lines less harder and more than lighter to your lines and touches in order to make them more easier to erase in your final lines. For most inspiration, please pick up a PDF of the Vilppu Drawing Manual, and if possible, please make a more tax-deductable donation to Archive.org, to help save the World's Digital Libraries. Have fun and have fun practicing sketching.

You have solid body proportions and line work, and your outlines are confident and steady. This is a great start!

I would start by breaking down the model into 3d shapes. A box for the torso, a box for the pelvis, and then connect them. After you are comfortable with general shapes, you can break down the form into more complicated shapes when you learn more body types.

The body is full of reference points that can help you have a better understanding of general anatomy. For example, when your hands are at rest by your thighs, they reach your (upper) midthigh and your elbow is generally parallel with your bellybutton. Your foot is close to the length of your forearm (from elbow to wrist) and there is enough space between your eyes to put another eye.

Once you break down the model, start pinpointing approximately where the joints will go. Because your goal is to have more dynamic drawings, I would suggest learning ref points for the body's joints (such as placing the shoulder and wrist joints down first, and using those two points to find the elbow in between) and getting the general anatomy down first (like the ribcage and pelvis, etc.) and breaking them down into basic shapes that you're comfortable drawing and are drawing consistently. Atfer that, then you can start exaggerating shapes in perspective and having fun with a dynamic style. Having the fundamentals down will only help you in the long run.

It' s nice how you add personality to the faces, takes them out of anonymity. I don't see your dominant line of action, but I' m a beginner myself.
