Add a Write On behavior to the B-Spline line (arrow) and that will animate it so it starts from nothing and then looks like it is writing onto map. Then you don’t need to keyframe anything and it is very smooth. Duplicate the b-spline line like you did and changes its color to black like you did for the shadow. MOve the control point like you did so the shadow is the right angle. They will both have the same write on behavior so they will animate together. Duplicate for the other lines. Hope this helps. Best of luck.
