Bob, yes, aberration causes the stars to "lean" towards the point in the sky on the ecliptic that the Earth is heading toward on any given date. Notice that the annual circular motion is for stars near the ecliptic poles and that linear motion is for stars along the ecliptic (not the celestial equator). Annual precession rotates the whole sky as a unit so, although it is larger and cumulative, it does not modify the angles between the stars.
