Looking at your new FH TS video I have some thoughts on what you can improve:
- You are using much hip rotation, but not that much power from the ground. Try to "jump more" off the ground without actually jumping off the ground with your right leg.
- Your arm motion is long (almost a full arm swing), it could be instable in a match situation and you wont be able to hit placements correctly. I would recommend keeping the elbow lower (and also maybe closer to the body) and using more forearm snapping. The chinese players also do this.
