Your voice could work very well for Exodus, but I think that it should be turned down a few levels. Think more like snobby child rather than whiny/tantrum child, at least for that second line. If it was meant to be yelled, the entire sentence would have either been in caps or have an exclamation mark. Also, the octave on that last line might have been a tad excessive, However, I thought that first line was very good for her.
