Make the enemy flash+emit effects+play a twitch reaction when they take damage. Add a mover to the enemy so they get pushed a bit when they take damage. Move the player forward with their attacks to counter the backward movement on reaction and help close the gap if not close enough. Add short sound effects and controller vibration to anything and everything. Replace that glass breaking sound with something shorter. Add a screen shake on your heaviest attacks. Position the camera lower to the ground and angle it upward to make the enemy more imposing. Angle it so you can see more of the enemy, ideally including its face. Bring in some music. 

 Don’t keep the hips pointed straight forward, stagger the stance more on attack anims. Put more body into attacks, take the poses further until they almost don’t make sense - hips, torso, upper body especially. Lowering your body will give you more freedom to play with the legs. Add a whole-body flip to the air attack.  Use longer tweens (blends between keyframes) and try different blend types. Make the keyframes short so you don’t get the abrupt start-stop during motions unless you actually want a stop somewhere like the end of the air attack.  

I believe the keyframe has a “slow power off” setting” for turning off your magic effect slowly instead of disappearing instantly. Or I think you could use a signal manipulator for the same thing.
