"In both versions of the story she is portrayed as elegant, sophisticated, capable of sharp anger, occasionally cold, and fully dedicated to her duty as a Sailor Soldier...She is portrayed as a very polite, calm character in the series...Michiru is also graceful and delicate, with an aura of sophistication. She is clearly intelligent, and this usually manifests itself through art and music. Usagi (to whom this observation is especially relevant) once commented that Michiru was the ideal example of a princess." -Sailor Neptune Wikipedia

Sailor Neptune should have a mature, caring voice. Very level headed.

You do not have to copy the performer's voices, but rather just mimic the essence of the character's voice. Sailor Moon should be cheerful and bright, Neptune should be calm and mature, etc.
