Rob Liefield’s drawings, it looks to me that he is skipping the first step used in life drawing, which is to draw the stick figure, followed by the basic geometric shapes found in the human body. Then he could get the body alignment right before going into all that detail. That Captain America drawing is just BAD. The perspective is off, as it looks like his chest alignment is going a different direction from the rest. That’s why his neck looks like it’s coming out of his shoulder.
