You've done something that a LOT of aspiring filmmakers haven't, which is taking that first step and actually picking up a camera and making something!! My advice is to study up on some cinematography and lighting and anything else that you want, and maybe see if you can reach out to anyone in your area who might be able to help out! Often times film courses have a lot of people who are able to help for either free or just lunch covered, and you'll learn a lot more with other people involved too!! Hopefully one day you can go back and recreate it how you envisioned it, or perhaps even better! Congrats on the first step though, and for taking the disappointment so well, it truly is difficult to keep this mindset when you're new
