WARNING!! ALERT! ALERT! I speak softly - even when shouting - so you may need to  raise your volume to hear me speaking.  Alternatively, you may want to mute the video, as I really didn't have a script and sound completely awful.

This is what the model looks like after a mirror and a tweak of the mouth area again within Silo2. For this image, I did not add or change poly flow, I simply re positioned the verts for a better look in the mouth area.
