Great goal! Start with Bruce Timm and Ghibli art tutorials on YouTube—Ethan Becker and Toniko Pantoja have awesome guides for both styles. https://geometrydash2.io

Check out Alex Grigg! He's a great YouTube resource for animation tips in Procreate! For style tips, you could start to study the particular art from each of those three art influences that you find interesting! I love Bruce Timm's Batman: The Animated Series, but he has SO Much more in his body of work! Look for what you love about Studio Ghibli, Disney, and Bruce Timm and save your images to a folder, or start a Pinterest board to keep track of them. It's great to have art that inspires you handy when you're drawing, so keep digging for art that you love, and start to play with Procreate! Here's Alex Grigg's animation channel, tons of great animation instruction! https://youtu.be/hzbmlyGDJO4?si=oUiRRcMDYq4v1Nb4 also check out Aaron Blaise! He has a bunch of great animation resources, and he even animated a short in Procreate Dreams! https://www.proko.com/lesson/procreate-dreams-animation-tutorial-with-aaron-blaise/comments
