by making it real he means realistic. the stuff just looked...not very good. its hard to tell with the small amount of animation there was but the kick needed more force and the punch just didnt look like a punch. also add an enemy so we know what your reactions of the other person look like.
it's sometimes best to actually remove frames, like have his legs just about crossing over for the kick, and then jump a few frames to the fully extended leg, this makes it look like he's kicking really fast.
