Don’t really remember its’ name, but the one where she hits them in the stomach with the shaft of her weapon, and then twists their arm around. Because the only thing connecting their arm to the shaft of the weapon is their own hand holding on to it, they would loosen their grip the second their arm started hurting. So while twisting the weapon around like that might be a decent way to force them to let go of it, actually breaking their arm that way would be impossible.
I suggest to instead make it so they let go of the weapon, then she quickly jabs them in the face or once more in the stomach with it before doing the kick.
Other than that little detail I really like the execution though. The blunt force to the stomach and the stylish kick, followed by a twirl of the weapon is all very cool, but people don’t tend to hold on to something that’s twisting their arm.
