To improve his posture, Raul must retract his scapulae, which means pulling his shoulder blades back and down towards his spine. This will help to align his spine and keep his shoulders from rounding forward. Lateral or medial rotation of the humerus would not specifically target his posture, and depressing the scapulae alone would not be enough to correct his posture.
