Points I should Improve next

After the toturial on Thursday, there are some key points that I should improve.

• overlay a texture to make the animation look not so digital. The texture could be scanning paper or recycled materials.
• More character in the butterfly's flight.
• Soundtrack should be added in. Industrial and real sounds could be used in the soundtrack.
• Use the butterfly to link the scenes.
• The idea should have impact and focusing on one part.
  

And I try to add a texture by scanning in the animation.
