Good for first but...
Even though it was your first time I won't just give you the A.
It was particularly good that it wasn't just a silent stickfight, and it some plot I think.
However the lack of a background, and the simplicity of the animation didn't help you with the score so you got a 3, passable.
It is still better than most sprite & stickfights on NG submitted daily so I encourage you to do more and better work.
