Proper way to make a drink

My cousin and I made up a drink (We THINK we made it up), and are looking for a bartender or mixologist to tell us the proper way to make it. We currently just throw all the stuff in a glass in no particular order and stir it. Wondering if there is a proper order to add stuff, if it should be shaken instead of stirred, etc. Here’s the drink:

A shot (or a little) more of bourbon (we use Angel’s Envy) 1 teaspoon simple syrup Fresh lemon juice (to taste…I like it really tart but not all people do) Ginger ale

It’s delicious, but I wonder if we can make it better?
