For the last few weeks I have been animating the major scenes for the cartoons. I have imported all of the backgrounds and assets into the After Effects file and then animated each scene at a time, while referring to my storyboards for placement and size reference.
For the characters, I duplicate the initial composition so that whenever using multiple compositions within scenes, any changes made will not change the values for other scenes. I then animate the character separate to the scene. Below is an example of the composition of the crow being animated separately to the scene.
Here you can see the crow within the scene after being animated separately.
