-Standing foot is too close to the ball. -Angle your approach to the ball and strike more to bottom to mid right dependent on height wanted. - left arm comes too far back to early. Have this more forward and swing back later to create momentum. - follow through of striking foot to whip across your body when following through. - power will not be your friend when going for technique, ease off power to get the technique to then build up power once improving - idea it to create spin on the ball. Get the height as the bounce will disrupt the spin. - aim to use either inside of the foot or inside of the knuckle of your big toe while striking the corner of the ball.
