I chose to study a photograph with a highly unnatural pose and fabric preventing me from discerning the back leg very well mainly because the arm and front leg were situated in a way that I did not have any muscle diagrams that matched. I wanted to try figuring out where they would be located.
When I drew the gesture, I drew the overlaps in the upper arms backwards because I didn't understand how the deltoid insertion moves with the arm. I also noticed one of my previous studies looks like I connected the iliotibial band to the femur instead of the tibia. Lots to learn.
