Look to fix my drive from square one. Standstill. Is my timing right?

So i have come to realize that my throw needs to be reworked from the ground up to remove old bad habbits.. Well they are only 2 years old as i have only been playing for 2 years.

Here is a throw i felt was pretty good Distance wasnt amazing but i think good for my level.

Here is a slow motion, Im really hoping that i get the timing down and then ad other fixes..

can somone let me know if my reachback timing and momentum tranfer is right? Am i losing potential anywhere?

Thanks for the tips in advance!
