Cheers for the advice. Do you mean hold my weight on the back foot when the bowler releases the ball with only a half step front foot? I will definitely be working on the trigger movement next bat. As I said to @Buzz I was unaware that I had a trigger movement. Cheers mate.
I think if you finish the double tap a bit earlier you can complete the forward press a bit earlier thus being still for a fraction more before delivery (it looks like , on occasion , at point of delivery , your feet are still in the process of doing their trigger .... sometimes it looks like your bat hasnt reached the top of its backlift (is still on the upward arc) aswell because of the lateness of the tap).
If you were still , at release point for a fraction longer , then you could get a bigger stride in forwards , and not look pinned on the crease/only having a small/half step forward . Also , if you were still for that fraction longer , you could move further back when deciding to go on the back foot .
In terms of the trigger/front press itself , i don't think its how big or small it is , rather that if its not completed early enough , your weight will be taking you to that predetermined position during delivery , at which point its harder to adjust to going fully forward or back etc .
Perhaps , expermiment with your tapping a bit . You tap , then wait , then do two or three quick , light taps right at the last moment.....as an example, if you did one less quick tap at the end , that might give you that extra fraction of a second to complete the trigger before delivery ( this is actually an issue that steve smith worked on early in his international career ).
Having said all this , its only a small thing , like i said earlier , your batting in general , looks really good . I like how compact you are and you keep your shapes really well . You look like someone with time at the crease , so if you didn't deprive yourself of a moment via the lateness of the trigger , you'd be the kind of bat that looked like they had all the time in the world .
