The idea failed :C
But I will share here my failed results…
I wanted to create an animated base, for those people who don't know how to animate in After Effects.
By creating your character using my base and uploading this file to after effects, a person could already get a ready-made animation of his character created from my base.
At this link you can see what the animated base looks like and the unsuccessful animation of the character created using this base:
