Re-arranging Seconds

To get a better feel of how my animation will look during the time frame I have quickly drawn up my key frames and inserted them in to After Effects. I feel that this process makes putting my animation together far much easier than thinking about it off the top of my head.
I have also included the cut out of my chosen part of the song to also help me with getting the right timing for each scene.

This is a screen shot of my key frames with in After Effects which shows each layer on the timeline which I can edit by stretching the layer on the timeline to make the layer short/longer. This process is quite helpful for if there is a change of mind.
My animation used to stand at a time of 30 seconds long and is now standing at 25.
