Not good
Google search for the picture of the Earth. That doesn't impress anyone. The missiles look rubbish, I'm sorry man, but the least you can spend on an animation is atleast 2 days. It wasn't animated very well, and looked jumpy.
So to improve:
Smoother
No Google (draw the stuff yourself)
Artwork (draw better)
and don't try this idea again.
I'm afraid that it doesn't get a save from me.
