Continue to practice your game. Visiting sites like this, bowlingballexchange.com, and bowlingchat.net, you can find very helpful insight into correcting a problem. I will let the others continue to critique your game for you as I'm an observer and ongoing student of the game, but no where near as knowledgeable as others. One thing I will point out to you that Mo Pinel taught me is that if you are going to have your hips open to the lane, make sure that your target continues in that direction. I think it was pointed out above, but you do have an exaggerated dropped right foot for a 5-step approach. This completely opens up your hips whether you feel like it does or not. With such an angle, your target would really end up on the next lane, which is fine if that is how your are going to play the lane. By the time you reach the foul line, your backswing/follow-thru has squared towards the pins but your lower body remains open to the lane....can you see where this creates body angles that fight against each other to complete your swing?....determine which type of bowler you are most comfortable being....if you are more comfortable with the dropped back foot...remember this promotes swinging/opening up the lanes....if you are more comfortable with the square follow through towards the pins....you will need to bring that right foot back even with your left, to allow for a more matched body alignment when you finish at the line....hope this helps. Again, I've learned and watched a lot, have had some good influences around me, but I'm no teacher or professional. Just passing on my observations in hopes of helping continued growth of a fellow bowler....good luck and keep us all posted!
