The line from the base of the horn past the eye moves out and away at a diagonal to the frame. The z axis seperation distance between the horn tip and the eye creates relative movement between the two as the view point is moved up and down. As the viewpoint lowers the tip moves towards the eye in a vertical plane bringing it closer to the diagonal line. As the viewpoint is moved up the seperation between eye and tip increases giving the visual effect of a greater seperation from the diagonal line. The problem comes from visualizing a 3D object on a 2D plane.
And no, you can't change the vertical viewing angle by tilting the picture.
PS - you could have chosen disingenuous.
