storyboards

The animtion I'm still doing is a silhouette animation.
My aim is to create a short animation which could raise awareness of the pollution issue and communicate the effect of pollution.
The animation is about a butterfly's trip in polluted enviroment. I want to make these ugly pollted things in a beautiful shape then the butterfly breaks these false appearances.
Here are my storyboards.

It's a sample I did that my animation should be.

The first sequence. A butterfly stops on a flower. Everything is peaceful, so I use light green as background colour.

There is a pond with lotus, active fish and small waves. The butterfly stops on a lotus.

Then water surface rises, the lotus and leaves are flooded.

There are some hills which are constructed by lots of gabages.

The butterfly flies to a flouriching tree. But when it stops in the tree, thousands of flies fly away. The tree is already dead.

Then many plastic bags come.

Some of them catch in the dead tree, floating in air.

Then we see the butterfly find a flower at close quarters. In fact, it's just smoke emitted from factory chimney.

The smoke surrounds and swallows the butterfly.

In the end, the butterfly is eaten and disapears with smoke.
