I just got done watching the trailer.
Like everyone else has said so far, some of the voice acting was a little too deep and just a little too unbelievable for it to come out of the actor's mouth.
That being said, however, some of the voice acting was spot on - specifically, "I'm here to see my mother" and "I hope you like flying." It was different enough from Hayden's to be good, and more fitting with Sebastian Shaw's voice, but not so different as to be jarring or stand out. You are obviously capable of making that voice - just do it more now.

Other than the pitch of some of your lines, which can be easily corrected, the only thing that stood out to me was Shmie's (sp?) scream - sounds too much like a stock sound effect, and a little too shrill and different from the actress's voice to be believable.
