Nice work! These have a good dynamic quality - you captured a lot of very diverse poses, and that's helpful for understanding the human form. The top right drawing shows a nice twist in the torso.
I think a next step would be to work on even shorter gesture drawings - e.g. just 30 seconds, where you focus on the overall movement of the form and ignore the details. Find the center line or line of the spine and try to draw that out first.
