Tweeks here and there
The animation was given good details and the way the characters moved was very realistic, even for stick figures.
The only problems I have with these animations is that most don't last long. I know this is your first, and it is splendid, truly, it is better than some who have been animating for months or even years and I praise what you have done.
However, your next titles should be a bit longer. Albeit the aditionnal effort and time, you can truly make a name for yourself as an animator.
Also, I like this style of animations, simple but effective, but there should be more highly-detailed backgrounds. This could allow you to use the environment as a weapon as well rather than just energy bursts or swords!
One last thing; the text. I don't know if you mispelled a few words here and there by accident or because english isin't your primary language but as your animations get more sophisticated simple mistakes like ''my'' instead of ''me'' will annoy people, trust me. Also, make thedialog a bit longer, not in term of content, but in time. Most of the text was displayed for a perfect time, but others were short. So short they only seemed there to add words.
All that said, keep up the work, you have a great amount of potential!
