I'm still not sure about the new banner. It's not a bad shot but my initial reaction (after the *OMG new piccie* reaction) was that it makes them look a little on the older side.
Personally, I'd like to see them being silly (something like the horsing around they were doing at Bristol in the videos that I've seen). Something that would really catch the eye of someone walking past and make them say "they look like they're having fun, I might pick that up and have a look."
Or perhaps have them doing something other than posing. A candid shot with them all laughing or smiling would be lovely
