I noticed that it looked like I am doing a lot of my overhead strikes with the palm up, instead of having the sai vertical and rolling it. Also, on at least two of my sets of double punches, the second punch of the set was not on target. Most of my middle blocks did not have the sai in front of my shoulder, like it should be. Also, the line of motion of the middle block close before the second kiai was very odd.
