It takes a lot of work to put a video together, so kudos to you for getting it together. Only non-technique comment I would suggest is it might help to add video of him catching from the side or front instead of primarily from behind the plate, even if it's not in-game and just practice. In some of the videos, the umpire blocks a lot of what you can see, especially for receiving and throw downs. The other views would allow you to emphasize catching skills and footwork.
