Hello there,
thanks for sharing your work!
It's interesting, I can see what you mean about the most recent sessions you did. It seems like you were focusing very well on the line of action during your earlier sessions. There is a lovely fluidity to the lines, and they feel much more alive.
Perhaps you could try warming up before the session with a very loose wrist. Try to freely draw some S and C shapes on the page, and loosen your wrist up to ensure you are not making rigid lines when in session.
Might I suggest also trying some poses where you draw a continuous line, instead of breaking the line by picking the pencil up off the page.
Finally, if things are becoming a bit too frustrating, dial the detail back completely and focus on the line of action, without heeding the details of mass, limbs etc.
I hope this helps! happy drawing :)
