I've seen this before.
Well, the story of this animation is pretty much the exact same concept from James Lee's "Make Snacks, Not War". (The title is even the exact same, but with synonyms instead of the original words) If you wish to make movies in the future, I would suggest you make movies with more original plots, not that is a carbon copy of an already existing work. But onto the actual animation, the animation was pretty choppy, and felt more like an automatic slideshow. Things I would suggest you do is raise the framerate (12, 24, or 30 fps are commonly used) and add more poses in between drawings. Also, music would be nice.
