Very well-animated
For being a stick movie, this was one of the more impressive movies I have seen out there. You covered the graphics and animation very well, and you clearly have good animating skills. The backgrounds were also drawn very well. There was plenty of action with the main character, and I felt like I didn't really get bored during the movie, even though at the same time it was very short.
Another good point was the music in the background. It was the 300 music, but nonetheless it still made for good fight music. I just think you needed more sounds in the SFX department of the flash, otherwise nice job here.
My final comment is just saying that if you can do all of this with sticks, then I feel like you can make something way bigger with real characters. Good luck in the future with your flashes, and I'm looking foward to seeing further flashes coming from you.
