No, of course not. Actually the interesting thing is how you are one extreme or the other. Either you are completely on your back foot fading away, or you're stepping forward and then hitting a shot off of your front foot. From the short clip you posted, I didnt' see any shot where you're loading up your outside (back) foot, and then hitting through the ball while transferring your weight to your front foot. Given your style of play and the stroke you prefer, I feel like that would be something to work on.
