This is a good beginner/advanced beginner level turn. I recommend turning the right foot out before it does the flap when traveling to the right, and turning the left foot out before it flap when traveling to the left.
Tip: When you are trying to go faster with an even rhythm, try not to bounce up and down (up on the flap and down on the heel) as that will make them uneven.
