I have assessed the videos. The first video just made it look like you havn't played much cricket as you were basically mistiming the ball.
Some improvements in the second.
Big improvement in the third.
You are still missing the ball outside off stump - and getting leading edges to balls on your middle stump as you try to turn the ball to leg.
I have looked at your backlift. Not your pre-delivery backlift which is fine. But your real backlift you do before you hit the ball. It is a bit crooked and goes out to slips too much. This is leading to you missing the ball outside off stick - and having more trouble timing the ball on middle stump.
Take 15 minutes and practice your backlift - do it once or twice a week for 3 weeks and you will fix the problem. I can't remember if the coaching manual says to take your backlift over off stump. So hopefully someone else will come along and make a post to confirm this.
Sunil Gavascar in his last match which was a benefit game. Spent 45 minutes before the start of his inning practicing his backlift. If he thought it was important so should you.
All shots start with the backlift.
