Drawing the Mouth.

Ah, the mouth expressions, sometimes it easy to forget that the mouth does move, I'm guilty of just doing a open mouth in many drawing, we (artist) have to remember to keep a library of images to look at and keep in mind that we need to add just a little thing to make the drawing pop more.

Here is a cool on I found on Deviantart created by an artist named Night-starker13

Enjoy!
