Changing technique is not easy. I've done it myself and actually binned the advise I got and worked it out myself, but it took a year and old faults still creep in.....however I did manage to correct faults most of the time I'd had for years.
You have a remodelled technique you are happy with ....tick box.
Accept batting is hard,staying in is hard, scoring runs in hard I a real match....have you ticked that box mentally?
Are you prepared to work hard in the nets and are you determined to improve your batting? Tick box.....
is your attitude right? Can you be patient enough to understand it takes time? That box needs ticking if it's not ticked already.
So you are left with minor technical issues to improve on after already making some big changes and a determination to keep working and keep practising.
If I were you I would think of one issue alone and work on that at the next net, there is help available none of us are that good but their will be common issues that come up.
One thing I've noticed is when you are defending a straight ball it sometimes goes to the on side instead of straight back up the pitch, this is a issue I had and still have.comes with having a strong bottom hand,which you have.
It's worth practicing relaxing the bottom hand in defence to see if that works. This is easy to do and will either feel right after 20 mins or not. So it's a small change not a big one.
So it's easier to think of one thing to try.
The reason I spend a long time against the machine driving full balls is this is the weak are of my game, if the drive is working or I block it straight back other shots are likely to fall into place Because they are balance related....
The answers are in more hard work and patience....

I will feed the machine all day long for anyone, now I seem to have lost 10 yards of 'pace' in my bowling..haha!!
