Good graphics, unfortunately the script trashes it
The part where it was just the leaf and scenery was pretty.
But the over all execution of the toon gimped a bit. Pretty much the script.
It was out side the box, different but wasnt really funny because a leaf could really never do that.
Another chap I was helping had the same problem. Good animator but bad script writer. He wanted to do something so off the wall that it became sort of stupid.
You need a bit of "realism" when you do a script. Bugs Bunny is so funny because of the basic plot line. Simple and some what realistic. IE hunter hunting rabbits in the forest. Becomes funny because Bugs fights back.
A leaf would never ever do something like this. I think you should have stayed with the beauty theme, you were trying to combine two things.
Have a squirrel play with the kid or such. Then maybe a pretty sunset.
The leaf fight was alright but then when you went to the police and the scientist it tanked.
Maybe just cut it off at baby getting dunked.
