Hold the needle between the distal 2/3 and proximal 1/3 this will allow you to drive the needle across the whole target without the need to readjust (0:45 minutes, 2:29 minutes) Other than that your technique is good; you enter the target at the right angle and twist, you extract the needle with the contralateral arm. the only adjustment would be to hold the needle correctly so that you can take the needle through the targets in one swipe.
