He's young. Let's be instructive rather than critical.
Seth, part of hunting and being a hunter is following laws. The laws are in place to protect the game animals, the hunters, and the whole sport. Without laws we would not have animals to hunt or land to hunt them on. While I congratulate you on a fine shot, You need to do some research in order to start doing this right. I remember my younger days of carrying an air rifle around the farm shooting things, but those days are gone. Talk to an adult and get the info you need, then begin to hunt things. There is plent of legal game, squirrel, rabbit, many types of birds, and much bigger game as well.... altho you'll need more than an air rifle for those.
Once again, it looks like a great shot. And we do not want to discourage you from a love of hunting. But, you need to look into the rules and make sure youre legal!
Good luck in the future,
