'Soundbite Animation':

The third animation was where things started to get more complicated for me, when working with animating the mouth and body movements of these two characters (especially 'Young Actor'). 

In this scene, YA responds to OA's previous nonsensical line-reading with his own (equally-nonsensical) reading. This causes OA to shout, stop mid-sentence, then proclaim it's his own turn (to act 'properly').

A lot more motion was developed during the making of this scene, especially with the lip-syncing, which was taking up a large portion of my time.

The second animation that would be made was of the 'Older Actor' (OA) shuffling the papers of his script, the off-screen voice of the director calling for 'Action', OA delivering a cocky line to the 'Younger Actor' (YA), then YA responding just as confidently. 

The OA would then attempt to deliver a line from his script, which would now be out of context, to which the YA would look confused.

I had initially decided that I wouldn't use much lip-sync, rather just a simple open and closed mouthing system for the two characters. However I didn't like the look of it when done, so I went ahead and provided lip-sync for this animation (and also decided that all subsequent animations would follow suit).

I began work on the final animation, separating it out into several different sections to make it easier to work on. These final animations will eventually be cut together seamlessly, so there is a need to be consistent in character design, pen size, etc.

The first animation focuses on the initial walk-on by the 'Older Actor' (OA) character, followed by the 'Younger Actor' (YA) running frantically onto the stage, dropping his script and causing the OA to drop his too.

I finished up the keyframe animation, that would be used in the future as a basis for the final project. 
As I worked on this part, the drawings and designs of the characters actually grew in structure, until they became pretty much the final look of the two 'actor' characters.
