My recommendation would be to start any hunting/poaching questlines and just kind of wander the woods hunting. Not only will you discover treasure and immerse yourself in the beautiful game, but you make decent money, level up both hunting and the bow skill relatively quickly, and get used to the way the bow actually operates. There are a few perks that are really helpful such as one that makes animals a lot calmer around you. I’ve been able to literally walk up to the ass of a boar and one shot it. You can do it with bandits too, but I found backpeddling from bandits or riding from a horse and shooting all janky really boring so that’s just my opinion.
