Looks like you have a ridiculously strong grip on both the top and bottom hands. You can get away with a strong top hand, but not so much the bottom. I had a similar issue a couple of weeks ago, and I tried the Adam Gilchrist trick of sticking a squash ball in the palm of the bottom hand. It only allows you to grip the bat with the thumb, index and middle finger, and it worked wonders. The bat is closing because of the grip and because you’re playing so early. I reckon the reason why you take your bottom hand off the bat so often is because you can tell it doesn’t feel quite right through impact.
Also, when you try to be aggressive you’re even earlier on the shot, you lift you head up and take your eye off the ball and totally lose your shape.
Finally, you let your frustration at bad shots build up, and you get more and more frustrated the longer you bat. It’s easier said than done, but try and forget about the last shot regardless of whether it was great, or an absolute shocker.
Plus points... solid defence. Good head position at impact. The bat also comes down nice and straight when you’re not trying to wallop the cover off it.
