The pelvis itself is more of a rhombus like shape rather than a circle/sphere. Thinking more about how the anatomical structure is shaped while gesture/ figure drawing will improve your knowledge of how the human body works. In terms of the gesture of the pose, I feel like you nailed it down! I can see what the essence of the pose is and approaching your lines in a fluid manner, thinking about directions and looseness. The next step would be just continued practice as well as utilization of CSI lines. Also something to think about, think more about the directions that the pose is making and less about the contours of the body. The limbs, for example, show that you're too consious about the contours of the arms and legs and trying to render it in one go. Instead of that, think about the limbs as components or parts rather than one think. Overall, good job!
Here are some resources that may help you further!
When approaching gesture drawing, you have to look/feel the movement of the pose.
this is a good video explaining more about gesture/movement.
Think more about the movement of the pose (the direction of the arms, torso, legs, head, etc.) and just keep practicing! You'll get there if you practice alot.
These are great! good job for all 20 days. I can see that you're getting the essence of these expressions as well as the shadows forms of the face, proportions, and thinking three dimensionally. As for the next time, I think you're ready to move on from the 30 seconds expressions and doing more longer expressions to get more out of the face. All in all good job and keep pushing!
