It's a great video bc it makes your son look like a great player. Well done.
Dub's advice is good regarding picture with name and grad year.
Outlaw's advice regarding music is very personal. Remember that you want the coach to feel pumped up and think your kid is very energetic/full of stamina. A soft musical note may be less annoying but also creates a slow and gentle feeling re a player. Coaches can always lower volume or put it on mute.
I liked how you showed the weak foot cross and different various movements by your player.
The ending was good but a picture one side of the screen while displaying the accolades is good. Also, if you are sending directly to coaches, including phone numbers of references along with the email you provided would be great as different coaches have different preferences.
Since Coaches may not be able to go to games due to Corona Virus or travel restrictions, I would also include a link of a full game for them to watch.
