Just needs more work
Not bad for a second try, it's a decent idea, and with more time this could become really good. Try working with a higher frame rate, this usually makes a huge difference when it comes to stick figures, and it makes the animation flow smoothly, and doesn't make it seem jagged. One more thing, despite the videos flaws, you should try and make it longer. Especially with these kind of movies, the more we see the better. All you need is time and effort.
