How the Earth will end

So this is my first story :) and I made it up with my friend, Mads, while cycling to school.

It is about the end of the Earth and while making it up, we really had loads of fun, so I hope you have too!

Please comment, I want to improve my writing skills and my English ;)
And can someone please tell me how to make appropriate covers in Wattpad/ Paint/ wherever? I've tried, but it wouldn't work...
