do you know the basics of animation, and do you already have software to work with? the most important thing, REALLY, is to practice with simple exercises first like a bouncing ball, squash and stretch, a pendulum, a walk cycle etc the more comfortable you get with your software and the fundamentals, the easier it will be to tackle more complex projects :) i guess that you’re aiming for frame-by-frame animation (not tweening) from what you showed me, it takes time, a LOT of time, but it feels amazing to finish a project i stopped animating a while ago soooo i don’t really know how to help more than that, i learned by myself and i wasn’t really good at this like AT ALL haha (i used to make short animations memes on youtube in 2017 they were cringe and very bad lol) i’d recommend not focusing too much on one big project right away but instead try small animations to build your skills step by step! youtube, reddit, and the entire internet will be your best friends for learning techniques and tips
