It's not a mouthpiece. His lips are transparent (or I tried to do that!) to show the metallic teeth behind it; actually, I kind of liked the way the "mouthpiece" happened... But I couldn't isolate the lip section in Bryce so lost that effect... ANd I TRIED to keep the glowing eye, but somehow Bryce decided to group all three of the spheres in the image into one item, and I couldn't ungroup it, no matter how I tried... I'm still learning that program, often the hard way, it seems! Thanks for the comments.
