10 years ago I made my BiteyCastle Academy FX course to help me pay bills while working on my personal projects. It used to be $20/month, but TODAY I MADE IT FREE cos I like you. There's 14 months of content arranged as "Levels" of mastery, 52 lessons in total that will teach you 2D FX from the ground up. More than 21 hours of instructional video included, hundreds of diagrams and examples guiding you through from very basics up to very complex.
All I ask is that you learn that stuff real good and become a great FX animator. Also if you wanna donate, there's nothing I can do to stop you. Otherwise, it's free. Go nuts.
