what i do is make the key frames in this animation it was the first frame and the last one then i made the in between no effects yet then i made the impact frame (the white and black one that can be anywhere but i put it on the most powerful part of the animation) then i add effects aka the blue power on the fist then i adjust his eyes to line up and make sure everything is smooth then lastly i make a thumb nail and adjust the speed by ether adding more frames or changing the wait time in the code and boom your animation is done.
