1st of all welcome back . There is a lot of good things going on so it should be a fast road to scoring big.http://s943.photobucket.com/user/spr3wr/media/Untitled_zps4dc6cffa.png.html?sort=3&o=0
Starting left to right. Keep the head over the ball.
1st pic everything looks good. A little more side [censored] is needed, Think to keep your left eye over ball at the start and during the entire swing. Don't forget to keep your head over the ball at the release point.
2nd pic, nice crossover step and pushaway on time. Need to keep the head over the ball.
3rd pic,Nice footwork but the hand is starting to move outside of the ball. Try to stay more behind . You can see how far the head has moved away from the ball. Keep the head over the ball.
4th pic , the 3rd step didn't stay inline with the 2nd step. Try to walk a straight line.
5th pic, Head not over ball and hand is a little on the side.
6th pic, You lose your balance in almost every shot. Post the shot so you can see the ball roll over the target(red arrow). If your head is moving you cannot see if the ball is rolling over the target.
Don't reach up after the release think to reach down the lane. This keeps the fingers in the ball longer.
Keep the head over the ball/tilt. http://www.strikeability.com/learn_06.php
