Naturalness: Whether the motion looks physically plausible, smooth, and human-like, with no or minimal animation artifacts. For example, body parts should not unnaturally intersect, such as a hand clipping into or passing through the thigh or torso.

Expressiveness: Whether the dance is varied and expressive rather than repetitive or mechanical.

Music-motion compatibility: Whether the rhythm, dynamics, and overall character of the dance match the music.
