Here is a fish animation freaking out after seeing something and reacting to it. Doing some pantomime acting. Started out with thumbnailing the scene and then putting it into an animation. This process I learned when I was studying 2d animation at Aaron Blaise's website at creature Art Teacher. I acting got my 2d animation and character design certificate from him and his team. It felt like an honor and big accomplishment. Thanks Aaron! :)
Drawing was in Clipstudio Paint for the rough thumbnails. The animating part was done in the Rough Animator app. For both I used my Computer with my Wacom intuos tablet.
Final animation.
