She has 5 types of turns in both directions - Rocker, Bracket, Twizzle, Loop, Three
She had 5 types of steps in both directions - Toe hop, Toe step, Chasse, Mohawk, Choctaw
She has full body rotation covering at least 1/3 of the pattern in total for each rotational direction.
She most definitely has upper body movements for at least 1/3 of the pattern.
She has 3 different combinations of three difficult turns executed with a clear rhythm.
This footwork sequence is clearly Level 4.
