Mouth shapes study.

These are some mouths shapes studies I did for a mockup introductory alphabet lessons for preschool kids. They are supposed to show the differences between vows and consonants.  Where, in the vows pronunciation, the air flows out from the mouth without any obstruction.

While consonants, when pronounced are obstructed by lips, tongue or teeth.

The animations were accomplished with vertex groups and morph targets in Blender and Photoshop later on.
