tutorial on how I draw mouths. DISCLAIMER: I am not trying to say that the way I draw mouths is the only way to draw mouths. I am just trying to help people by showing a process and giving tips. My art style is pretty cartoon-y, so this may not help with more realistic art styles. The tutorial starts off simple, and then expands some ideas.
If you did not find this tutorial helpful, then I strongly apologize and will try to do better in the future.
