The horizon line is usually affected by the camera location relative to
the plane.  You have not included the camera in your code.  But if it is
anywhere aroung y=0 then a plane at y -500 would give a high appearing
horizon if the camera is pointing horizontal.  The horizon appears lower 
the closer the camera is to a
horizontal plane
