Even though the warning in the beginning was nice, I suggest you make your flashes in English in the future. Not to criticize Spanish, but it simply is a fact that this is a English site, not a Spanish one.
Putting language to the side, I think you have a long path ahead of you in the ways of flash. The animation was, well, bad. I could literally count the frames, which you can easily prevent when you use tweening. The slow framerate pretty much killed the whole action for me, which is the reason, including the language, why I am rating this this low.
2/5. 4/10. I don't think there's much else to add, but work hard and become a good (if not great) artist. I wouldn't be surprised if you can.
