im stuck i cant make my "top" bone curvers look like wayn'es "top" bone curves, this is not the body bone this is the top bone for the squash/stretch mechanic

i cant fix my paths or understand how to fix them to make them look like waynes, this is for the top bone for squas, my curve. i try and adjust them but i cant get the shape right
