Learning the combo till you don't have to think about it will allow you to concentrate on stylizing the movements to create different characters. So...

1. Learn the 16 count combination.
2. Use the music as a metronome to keep repeating the combo.
3. Repeat the combo until it becomes natural - drilling it, not until you get it right, but drill it until you don't get it wrong : )
4. Practice the combo starting with your right foot.
5. Practice the combo starting on your left foot.
6. Create a variety of arm positions and patterns that frame and flow from one movement to the next.
