Hello there! There are several indicators you can use to determine the angle of the pelvis. One is the shape of the clothing. This will help you know whether we are seeing the lower or upper part of the pelvis in that pose. But there are also other shapes, such as the obliques and the sacrum. The obliques rest on the upper part of the pelvis, while the sacrum is the central bone at the back. Hope this helps :) | Artwod Feedback
