This is the pose at the moment of punching. Let's draw it with the following points in mind. Is the large, curved flow from the body back to the left leg drawn backward? Is the relationship between the orientation of the torso box and the pelvis box captured? Can you draw the difference between the right side of the pectoral muscles, which are strongly pulled back, and the left side of the pectoral muscles, which are relaxed? Since this is a pose that may give a sense of fear to the opponent, you may try to draw it with a strong viewing angle to make it more powerful.
