Potential... only time will tell
You're sticks are well drawn, but your animation needs a lot of work. Here are some suggestions:
Text: People have to read... orange text is not only difficult to read, but it is also small. If you're going to make it like that... people need more time to read it... it moves too fast as it is. I'm not saying make like five seconds per line, but just make it so that it's easily read. Try voice acting it if you want... it'll keep people from being bored.
Action: Was too face. It almost looked jumpy and rushed. I don't know what your frame rate is, but I'd suggest either dropping it or fleshing out the action scenes so it looks like it isn't just blink, blink... over. I felt unfulfilled.
Animation: impact will create friction and force... you may want to add little effects here and there for when people hit each other, when their feet strike the ground... ect. It adds more to the effort of the animation and also creates some realism.
Not bad for a first attempt.
