I hope I don't come off like a jerk, but I have to offer some constructive criticism.
So, when they're running around with guns, everything is fine, because you don't have any shots that need to cut together.
But when they get into the fisticuffs, it doesn't cut together at all, not even slightly. None of the shots match each other. It's just a whole bunch of glaring unintentional jump-cuts.
My advice is that you spend more time rehearsing the fight scenes. Get your actors to be able to repeat the same motions, over and over again. Then, film them doing the same thing over and over again, from different angles, and different camera perspectives, some close, some wide, etc.
