I feel like you did a great job on your piece. Both have a good feel and have pretty good proportions. The second pose could us a bit of work with the arms and thighs because they seem a bit off but overall both are really good studies.

This is good! Keep up the good work with starting with the line of action and then building on top of that. I think you are on a good path in correctly capturing the overal proportions of the human form. I would continue to focus on sketching the building blocks of the body first and then adding the detailed contours. For example, build up the shapes and volume of the limbs first, before focusing on the final contour would help you more accurately capture the final details in the first figure's back leg.
