@ Tushantin: Yes, it really helps. Seeing his face makes me wonder about his facial expressions, which in turn helps my with the inflection and tone. I think the voice I had in mind suits him, of course there's always room for improvement.
@TheMage: Your audition was superb! I think Tushantin was going for a more high pitched, a little hyper, teasing seductress; which is common in Anime(I am only speculating, but that's my impression of Lilith). But you got the femme fatale voice nailed. It sounded completely natural, you are very good.
