Well, it's hard to say, really. It sounds like you have a consistent form, so it's time to test yourself.
I'm an advocate of doing some extensive roving/stumpshooting sessions to test your accuracy under hunting circumstances. You'll want to wear your hunting gear and try to simulate the shots you'll potentially make while hunting. Use one arrow and pick a lot of different targets at different distances.
Shoot uphill, downhill, sitting, squatting, twisted around, bow canted, from treestands, etc. It's also important to learn to shoot through gaps in brush, under/over limbs, etc.
What you want is to be within a feather's length of your intended target. It's also a good idea to step off your distances after the shot. You'll get a good idea of what your effective range is, and what that distance looks like in the field.
After you confirm your field accuracy, it's time to test your nerves and how you shoot under pressure. Small game hunting is an excellent way to test that. Squirrels and rabbits can really get your heart pumping.
Of course, you can just go deer hunting a see how you react to having one close. If you can control your nerves, and the animal is close, take the shot. If you're shaking like a leaf and can't catch your breath, don't shoot.
