Sounds like a lot of fun! More time behind the bow will help with the focus and nerves. Also, form practice (work on picking a spot/focus) and I think shooting 3-D helps. For one, you get used to some pressure (shooting in front of your peers), you get practice on animal-size targets in different scenarios and at unknown ranges, and you can learn how to better pick a spot on a critter.

So, when is the next hunt?
