Still needs work
I see you kept some of my suggestions in mind (I.E. the voice acting, background, and I noticed better perspective). I personally feel characters created with the line tool often look very flat and unprofessional. Try learning more technique with the brush tool. The story was somewhat more engaging, but I found many moments where I had no idea nor cared what was happening. For instance, the scene transitions that flash random characters made no sense. All in all, the whole movie still felt quite empty and lacking for large portions. Consider adding more atmosphere, such as sound effects not related to just the fight and perhaps more background activity to keep your viewer attentive.
Keep it up, I can definitely see improvements.
