Thanks for the feedback guys!
Yep, one of the big complications when i was bending was that branch at the back. It was pretty thick and abit hard to bend compared to some of the other branches. I was also pretty scared of pruning more of it as i thought i had gone close if not already over the max 40% before it starts reverting to juvenile foliage. I am still not entirely sure of what i am gonna do with that back branch yet. So i am gonna wait it out till next year and see how it goes before pruning more.
I will update this design as time goes on!
