Hi I´m still doing my animation project for my studies. Now I finished the modeling part of bart simpson(I know he doesn´t look really good but I´m really new to maya and don´t have much time).
So I would like to animate the mouth. I thought about the opinion to realize it via blendshapes, however I get stuck in tranforming him to get his mouth closed. When I do it, it looks really inorganic.

Would be nice if anyone of you guys got any suggests. Also what I could maybe improve.

Thanks a lot
