After struggling for ages trying to create the music for the animation I decided to instead put in ambient sounds and sound effects. It took almost an eternity to make it as the only music software I have is garage band and it was difficult to judge the exact timing when having to click play in garage band and then quickly flick screens to watch the animation with the music playing.
I then added the beginning and the end by simply drawing it out and photographing it again to get the continuation on the look of the animation.
As you can see in the final thing there are quite a few new elements I added in such as the bird living in the tree and instead of it getting stuck in the rubbish and dying I thought it would be more interesting if it flew up to its nest and then have the monster shoot some rubbish at it and then it unfolding whilst falling down.
