You've got talent. I'm not really following this as this is the first thing I see of this (therefor its kinda boring for me). Pull everything together and release it as a full lenght feature or something. That would be...cool...
One tip: There are unnatural pauzes between dialogs. A way to fix this is to record everything in a DAW (Adobe Audition, audacity, take your pick) and export a scene into one mp3.
Not only does this take care of those weird pauzes, audio-events clitching up the place, etc, it will also severly reduce the file-size. Instead of having 60 0.3 mb mp3s you have 1 2 mb track.
