Not too bad for your fifth editing venture! You were able to tell a complete story, which was good. The only thing that really got me was the audio. Especially the music. The music you've chosen just didn't feel right - too fast, too loud, and not the right fit. And the guy's narration wasn't clear at times. I found myself turning the volume on my computer up, then down, then back up. You don't want your viewer to have to fiddle with their volume. I would go back and take a look at leveling out all of your audio levels as your first order of business.
Other than that, it looks pretty good. I would have liked to see the guy's face, but you may not have that shot. I especially liked the graphics - had the feel of a "real" printing press. Very cool and original. On that note though, I would make the full screen graphics move a little quicker, as well as a few of the cuts (the entire thing could be 1-2 minutes shorter). A quick fix would be to shorten the ending credits a bit. Just a thought though.
