After some research I finally discovered the 'Puppet pin' tool in After Effects. It answers a long time question of me concerning the making of some 2D animations. The latest example is the Dutch short 'It is not funny, it is art', in which the animation is mainly done by deforming the shapes in an organic and quick way. I think the 'puppet pin' tool is used for that.
I also put the storyboard and new character designs I made. The story is an endeavor to poke fun with Bing/Jose couple. I am still not so happy with the character designs. Not much of style in them. Have to try more.
