More work on Pelvic circles(lower torso rotation, exterior pelvic rotation circle step) Vs. internal pelvic rotation.
The Exterior Pelvic rotation describes a movement that is round like a ball. The hips are pushed out and around the center of the body, where as the interior pelvic rotation is internal and stays centered. The Umi has the pelvis moving up, and back toward the inside. it creates almost and indentation(concavity) in the lower abdomen.

For the circle step the legs should be slightly seperate (the length of one of your feet apart). The knees will straighten when you come around the back. Knees soften slightly when the movement moves around to the front. Think Hula Hoop, but only a little bit. come around 1 and 1/2 times and stop. the inside foot comes up on the ball in showgirl posture, the knee bends and you pull in your lower ab to accent that hip. The hand pulls up to the forehead to accent the hip that's working, the other hand extends out to the side, with energy, but describing a slightly languid attitude. Keep your lift in the chest, but slide it slightly away from the hip that's being accented to give a longer line. This movement can also be performed at a diagonal, moving so that in the end your hip accent is done in 3/4 pose.
Can also move in 4 directions. You change your direction with each circle, thus your circle will happen in one direction when facing north, the other when moving west, etc...

Combo:
8 2tension back
8 3/4 forward
4 basic
4 circle step
hip lift around
then hip lift forward.
