Jesse, keep up the long range practice....it will pay off.
something that alot of guys who learn the Hill swing draw form don't realize.... it is important to shoot at a target at long range where the bowarm is elevated to a horizontal position, or shoot at a target backstop that allows the bowarm to be horizontal, either way works. It is imperative that the brain and hand/eye coordination learn the total time elapse of the full swing. Shooting a swing draw at a lower placed target doesn't allow enough time to elapse and the shot happens too quickly and bad form develops almost immediately.
Swing the bowarm to a level position while drawing, release, and make sure you hold that form until the arrow is in the target on a long shot, or after the arrow is in the backstop on a short shot. I see way too many guys shooting at a ground level target and then drop their arm further after the shot. bad stuff.
Also, shooting at longer range targets allows the mind/hand/eye coordination to learn about arrow flight and trajectory. There is no challenge in shooting a longbow if all you ever do is shoot close enough that the arrow flies flat to the target....10 - 18 yards...woopee, the arrow went in a straight line. hard to figure huh? go out and shoot at 30 - 50 yards and learn your trajectory and form. I promise, it will help your short range shooting. Like Hill told Schulz, who repeated it..."what's your arrow doing at 30 yards?" most guys today don't have a clue. They never shoot past 20.
