avoid cell animation like the plague...

There was a part in the animation where I wanted to make the mouth of my character move however for me to do it with great detail from a 2D flat surface it would make sense to make a cell animation, but after doing the workshop I was terrible, so I had to figure out a way how to create the action of the mouth opening and laughing.

I did this tester to make sure it looked ok...

These are the frames which make up the short clip....

I am happy with this method and I am happy for it to be included within the animation. I like the style of the plastecine being carried through to create the teeth, it was weird when I was making this, I felt nostalgic feelings when I made the clip because it reminded me of Wallace and Gromit series, just the shape of the teeth,even though this was not my intention.  I just need to make sure that I edit it properly when I putting the animation all together.
