The anatomy of the torso and legs looks so good! I love the knee and the attention to detail in the feet. The armpit area could maybe be refined more. Adjusting some of the overlapping forms and adding in the coracobrachialis muscle may add more dimension to that area. The coracobrachialis is a really interesting little muscle that connects the inside of the scapula to the humerus. It is only seen when the arm is raised like this. I hope this is helpful. Keep it up!
