what is this,i doesn't understand
Is there a story or article where this is used in? If not then I'd say hyperbole. "Ice storm of glass" is heavily exaggerated.
That dose look good. I would take out from "...or based on facts". Art is mainly based off of opinion. I would say that "Art and what it has done has changes the world greatly."
Hopes this helps.
