Keep talking to the folks at the shop. Look into the traditional club in your state and look into gatherings. They are a great place to tap into help and people.
There are a lot of good books and videos out there to give some visual instruction on form and different techniques. “The master of the barebow” series packs a lot of information from different people on styles and form. Even youtube has some videos.
Overall just work on the basics of form and enjoy yourself.
