not sure what thread your using you have two up now but here it is again.
i'm no expert but just a few things that maybe others can agree with.
I think it would be a good idea for you to work from the stretch more and practice leading with that front hip and getting down the mound quicker. you stall a little at the top of your leg kick and lose momentum.
also I think your hand break/separation is way too early causing you to begin cocking your arm before your even half way down the mound.
work on getting more consistent with your rear leg extension ( ankle, knee, hip pushing off bringing your hips around) just before front foot strike. some time you did it well other time the rear leg collapsed.
over all your motion looked very smooth and repeatable
