I think the cover matches pretty well with the short ending of the trailer. Where it goes from being vibrant and fun to sort of dark and forlorning. I love the way they are all staring out into the distance looking a bit dreary, possibly nervous or worried about something that is completely unknown to the viewers. It could be absolutely nothing or it could be something they are afraid of, but the part when Gerard masks up and says "Let's go" gives me chills because whatever it is, at that point they pretty much decide to go into it head long. It's actually my favorite part of the entire thing. So yeah, I see how it fits for the cover as a whole. For whatever reason though, I was just thinking they'd go with something different.
