After a lot of delay, I have been able to work on the animatic, by taking Alan's advice of using footage from other animations and films onto mine to use as a choreography for my piece, I began editing scenes that I felt that i wanted to add into the animation. So with no further ado here is the 1st version of the animatic.
I have added a few notes for more information.
Meanwhile I have been working on the initial sound effects that will be added on the beginning of the animation, before the character enters the cake/ abstract world.
Here is a quick update of the animatic with the extra line in the end, it definitely adds more mood and atmosphere to the animatic and closes better the animation.
So after sorting out the audio, i went on the tried to recreate a new animatic, with Phil's advice, I attempted to look at the story in a different way and create a animatic which basically will focus on the objective of the story and not all the elements and stages within it.
I think I'm going in a better way now, though It may still need some changes.
