The most important improvement is the one you are already doing, practicing with a coach.
If you are hunting super thick terrain for WT then a stand could be number 1 but I would personally say a RF is more vital to success. I have killed a lot of WT on the ground including a bunch of B&C grossing bucks, it can be done. Guessing range in high stress situation is not as easy as backyard practice.
Either way, you are on the right path with your practice regimen, Dud has a lot of great info for you to absorb.
