I really wouldn't trim much more off that plant. You can already see the floor brought the canopy so there is no reason to defoliate any further.
I'm all for selective pruning, trimming is a great way to help control the plant. It lets light and air into Your plant. But the leaves are there to do a job.
I hate seeing people striping all the leaves off their plants. You plants worked hard I make those leaves for a reason. If you cut them all off they can't do their job as well. And the plant tries to grow more which takes more energy it could be using to make buds
