Super difficult subject matter you've chosen to draw, really great job at even attempting something this difficult. I tried to add some power and energy! Kaido being a big unstoppable force and Luffy clashing against him. Start learning about gesture and simplifying anatomy into simpler shapes. A big part of making a fight scene look cool is the use of perspective and gesture, but crazy perspective can be a difficult if you don't know how to turn forms in space. Great work keep going!
idk if wild perspective is the first fix, maybe one clear action line from luffy's head through the torso into the kick so the pose reads as one hit before you twist the camera
maybe lock one big push line through luffy's torso and fist first so the hit reads, then simplify the limb twists around that
