Have you worked on your lead arm some? Getting it to stab down more over the hurdle and then sweep away. Arm can have some bend, but your lead arm looks like it never even opens up far past 90 (not an effective counter to the rotational torque of the trail leg and also stabbing down helps the opposite side of the pelvis from the lead leg reach to control rotational torques imparted by the lead leg). Watching your faster hurdles the most glaring running/hurdling issue is controlling rotation off the hurdle. Shows up here as well as you can’t be super aggressive finishing and running off the trail as it would rotate you a ton. Your doing a lot of good things, but that is technical area I’d work first.
