The animation and graphics are good... no argument there.
The reason for 2 stars is that stick figure fight animations are so cliche and overused. There are *millions* of these out there... there needs to be some substance or innovation aside from copying *verbatim* styles you see on videogames.
To really make these stick figure anims more than just a "one and done" forgettable compilation, my suggestion is to try developing a new, original fighting style or incorporating more clever and interesting choreography. It will separate you from the crowd.
