A good follow-through is critical, especially if you want to hit the ball far. Follow through the entire swing, even if you miss the ball. This will get you into the habit of always following through on your swings. If you don't follow through you could miss the ball or pop it up in the air for an easy out. Nervous energy can throw you off your game and cause you to make mistakes. Practice regulating your breathing and visualize the trajectory of the ball as it leaves the bowler's hands. Try to block out any excited or nervous energy from the crowd and team members by concentrating on the ball. Before you practice with a ball, you should try to perfect your swing in front of a mirror, which is also known as shadow cricket. Seeing yourself will let you know what adjustments you need to make to improve your stance and swing. Make adjustments to your stance when you notice that you're doing it incorrectly. Throw a tennis ball down on the ground and hit it after it bounces. This will emulate a full pitch, or a pitch that lands right in front of you, and will help you practice swinging if you don't have anyone to practice with.  Keep your dominant hand on the bat if you are practicing alone. Doing this drill will help improve your bottom hand grip. The best way to get better at being a batsman is active practice with your team. Make every effort to attend practice. Drill game scenarios and hitting as much as possible so that you're prepared when game time comes. Take your coach's advice and listen to any input that team members have on your hitting.

Summary:
Follow through with your swing. Stay calm while you bat. Swing the cricket bat in the mirror to perfect your swing. Practice batting by yourself with a tennis ball. Drill with your team as much as possible.
