This is a sketch of the lines in the two photographs in the exercise. The right is of the bull fighter with the red line being the strangest form the top right to the pole to the back of the bull. There is also the line of the man's body and the second pole. The right sketch shows the main line as the eye line from the man to the direction the two horses are looking. There are secondary lines of the man's body and those form the horses heads to the bottom of their legs.
Three photos I have taken and underneath a picture with the implied lines in it.
