Points to look for:
- The shoulders, hips and waist have all turned a little more to the player's left, which will reduce the amount of movement necessary to get into a neutral ready position.
- As shown by the small blur trail, the ball not moving all that fast, but it has heavy spin.
- The player is watching the flight of the ball, to judge how successful the serve has been.
- The ball has bounced very close to the endline of the server, which is typical for long serves.
