Opinions on my WWI History Project?

Frankly, I think it's not very tasteful. You've obviously worked hard to produce the lyrics and match them to the backing track, etc but bear in mind that we're talking about a conflict which claimed over ten million lives and whose effects are still being felt today - some people would view what you've made as being disrespectful. The basic concept is a good one but I think that setting your project to "Bad Romance" isn't a very good idea, given the song's over-played nature and controversial connotations. Perhaps it would be better to set the lyrics to a piece of music which is more sombre.
