I did realize while writing my post that there was one necessary detail you left out, and that was the footwork. The positioning of your feet is extremely important when it comes to both the power of your attacks, and the stability of your defense. Since you left yours out, I had to make an assumption based on the rest of your attack and go from there. As much as possible, you never want to leave things like that up to your opponent, as it then becomes very easy for them to gain an advantage.
