Nice job. Character designs are okay. Backgrounds are a bit empty. You should take some time to fill them with interesting things. Use reference to help you with that. Also that window in the last scene would never be crooked like that. There are better ways to make an interior look run down. Animation is nice and snappy for that fighting game feel. For all those fast actions, I would suggest using animation smears/smear frames more liberally. It'll smooth out your animation and help visually connect the movements.
Again, good job. Hope you get to finish your project.
