Well done! Most of the poses are quite accurate. I’ve added a few quick notes to your first pose, in which you’ve already noticed the alignment issue. In this one, the contour lines of the lower abdomen are facing the wrong way. First, start with the alignment of the shoulders and the hips, then the tilt of simple boxes will tell you which way the contour lines go. To help you visualize the alignment, you can try standing in that pose and notice how the pelvis is tilting towards the viewer because of how the back leg is holding most of the weight.
