Man, i love the idea. The character design is just awesome, but.... well, the voices are poor (i'm not talking about spanish, but the audio quality). The episode is short, the movements are robotic and i think that's all for now.
But don't give up yet! You got a pretty good future, but need to work on those things i told. I'm look forward the next episode.
Well then, if you plan to do an animation based on fights, try to make them look a little smoother and i'm sure it will look incredible!
