Doesn't deserve that low, it's nice you got the decap, but yes, try relaxing more, it naturally makes your moves less robotic and more fluid. Other than that, try and make it a habit to not grab very much in madman replays, and try and make decap or split cap replays grabless, also try and make your second kick work with your first kick, this adds more style and smoothness to the replay. if combos work together it looks marvelous.
