Well, technically,

I did singlehandedly invent and discover how to write American animation action-fight scenes in screenwriting form (that isn't just storyboards and no script), though I am happy with that accomplishment, I still feel I have a lot left to do. Who knows, maybe I'll write and illustrate a tutorial some day. I had to build my action sequences from the ground up. I made all the fight and fighting descriptions, for my action series, up. And in the grand tradition of Shaw Brothers and Jackie Chan, I definitely feel like I could write a million more scenes and sequences. Most people just draw it. I write everything in great detail. But one can also benefit from drawing a comic or storyboard sequence on top of all that scriptage.
