OK, I dug up some old and a few new attempts with convex and concave lips.
As we know there can be a lot of variables in action and depth with just one lip shape- I wonder why it's not used a lot more
''Text'' is on each photo, just in case I can't post this many pictures here -----hope this is legal, otherwise I will post them in my attachments, or somewhere??
