I decided it was time to turn my scribbles into an actual script.
I had thought that it would be quite funny if at the end, it went to live action, and it was revealed that the guy having the rant was a guy in a rhino suit collecting for 'save the rhinos', and that he was in the pub having a beer on his lunch break. Unfortunately this had to be cut, because as I went through the script, it became apparent that it just didn't fit. Shame though.
Feels good to have a solid script now though, things may still change as I animate, but at least I have a good outline.
