Wow talk about your 'starting with a bang withering to nothing' situations....
Did they ever hire people to help Pia with her stage persona? I like her down to earth personality and she sounds very intelligent, but, IMO, from what I've seen on and off, she is lacking ....something, that grabs attention as an onstage performer...
She's got talent, intelligence, beauty, and charisma...just not that on stage presence... I can't say exactly what that something is, but I believe it's something that can be learned or 'fixed'.
Good Luck to you Pia...hoping for the best
