Since I couldn't work on studio projec ( because of the snow in the way to take the relevant files from univeristy) here again I come back to the soundtrack I'll be transcribing in the future project. After having talked to Alan, I decided to return to the music and analyse its rithm because it then suggests the structure of the story. This was done before but only intuitively. But now it is dead clear how to plan the action of animation.
I think this analysis might be very helpful to the following processes , I'll use it as a guideline.
