I do a LOT of walkback practice as it help build a good sight picture in your head.
Find a target size your comfortable with I use 40cm Hunter face beccause it's black with white spot and makes it easy to focus, start at around 5-10y shoot an arrow and walk back a couple of yards and keep doing this till you miss, then walk forward half the distance and start process again.
This keeps you focussed\\interested and most important keeps you in your comfort shooting zone while also spending more time shooting the problem,weak distances, if you keep track of how far back you get each day you can see your progress quite clearly.
Dont stop when you reach your target distance as the more accurate you are at long distance the more accurate you are at short distances.
good luck
