Finally we can see and comment your style
. First of all I think you have got very well the most important of the technique. The wrist motion and the final snap are very good. In regard to the movement of the leg like a baseball pitch, maybe it helps to get some more power, since it allows to make a forward turn of the torso more powerful when shooting and it would be interesting when it is tried to obtain the maximum range, but itīs very possible that it makes more difficul to get accuracy because you destabilize your stand and have to retake it at the moment of throwing. I think that a more stable position is better, though it may be helpful a short step forward when shooting.
When you start from the Greek position you move a little counter-sense the hand seizing the pouch and it looks useful to fix the trajectory since you make a single turn. When they are made more revolutions, the first one is just to obtained that.
In the vertical turn around style it seems to me a little forced that movement downwards you make to fix the trajectory. I would use there two revolutions without any doubt, but each one has to be comfortable with his style and if it is effective nobody can disqualify it. In general it seems to me that you have very well developed the shot technique, and to get better accuracy you need only to keep up a more stable stand, without moving so much the left leg. If you pay attention in detail to your movements, the snap is made when you already have both feet well leant on the ground and in fact the leg movement donīt add almost nothing. But the important thing is that one feels comfortable with his style.
Well, this is only one opinion.
Congratulations for your very good snap
