Vote a maximum of three times. Say "I vote for blue angel" instead of just saying "blue angel" If you really want to, you can vote for fics outside what is mention in the video, but unless you get top comment it's not likely you'll win.
If you must know, my personal opinion is that Red Thrush Private School seems like it'll be the best.

Go ahead ahead and vote here, although it isn't very canon: http://www.gopollgo.com/what-fic-should-doom-pie-read-next
