Can't add anything new on FH.
You are often bailing out of the BH. Wait on the ball and let the stroke go. Sometimes you just muscle it. Then you add this little flair of a finish with the wrist.
Yeah, it looks 'smooth' but you are getting it just over the net with very little spin. Your timing is good. So really stay down with your head and your right shoulder. Don't rise up too early.
