That's so exciting!! Art makes art!
Oh golly uhhhh. There's so so much to say in so many different departments. So. I'll keep it broad and of course anyone can ask more specific questions haha.
My go-to advice tends to be for creators to start as small as possible early on. Even if you aspire to create projects that are huge-in-scale down the line. So much about becoming a great artist involves moving through the stages of your art (whatever type it may be!) from start-to-finish, every step of the process, over and over and over again. So say in show creation, idk if you plan to be hands-on in every department or if you have a lot of help, but that could mean breaking down stories and outlining, writing, recording, constructing audio scenes and boarding, character and prop and background design, animating, music assembly, mixing, finalizing and editing, etc, over and over again. Obviously not every step may be involved in your project depending on what your goal is, but whatever it is that you do, do it sooooooooo many times.
While there's nothing inherently wrong with jumping in and making your first project something say, movie-length, or something immensely complex in scope, I do find it can, for many (not all) be limiting when it comes to learning a lot of fundamental building-blocks in craft. As well, I see a lot of people get lost in an overwhelming project, trying to focus on quality>quantity right out of the gate. But spending the majority of your time just on adding some extra polish as opposed to running through the whole process again and again can only do so much for you. Obviously, a mentality of quality>quantity is great once you have a strong baseline understanding of production. But again, I think it's a huge plus to work on shorts and teeny-projects to start.
Since the above is pretty dry, I'll add an additional fun one. I've found that a lot of newer artists will toss away the concepts that make them joyous in hopes that they can instead create something that fits an objective perception of "professional." Nothing wrong with that, but I strongly advise artists of all levels of experience to toss everything they've love about the world and other media into their work. Their favorite genres and tropes, the stupid inside jokes that make them light up with their friends that they can invite the audience in-on, adaptations of stories that have made them cry. Create the things YOU love to experience. It's fine to let go of what you think the audience wants. Cause that's not easily guessable. But what YOU enjoy is something certain to you. It's sorta like how they say, it's better to go to the gym and do an suboptimal-but-fun workout that keeps you coming every day than a perfect workout that leads you to quitting. Share your joy with the world, and someone will resonate!
Be silly, be cringe, have fun!
