For someone with no pitching experience - you did exactly what others do with expensive coaching sessions, tons of game time, and tons of assorted help. You thought out stuff, took your time to see "hey, maybe this'll work - give it a shot," stuck to it and grinded out what you had to do.
First off - congratulations. Second - most will say that you had a lucky day. Those that say it's luck are talking about themselves, not you.
Your the one that people like me look for on church leagues, small town leagues, backwater pickup games and so forth. We'll make a mental note when we spot a guy like yourself, then formalize our observations on paper, then track you, discreetly so as not to show a presence. Then, as you groom your self to actually approach this game and the pitcher's position as a CRAFT, you'll take this to a new level.
Stay with this, study the why-n-what for, give yourself time to think ... I mean think about how you did the game before and then keep a notebook of sorts of your experiences.
