OK, so, Mick's is exactly the same (good, it didn't need to change). The hannibal one is mostly the same. The pinhead one is the same. Clown is the same. One appears to have gone a bit more 'harlequin' to before, but otherwise not a lot different (and still more than a little gay).
Corey's is terrible (he's in the middle on the group shot). What the hell was he thinking? Joey appears to have added Jesus' crown of thorns to his for no apparent reason.
Then there's that one that looks like the huge heads from Rob Zombie's Sinister Urge album artwork. He'll be the mystery guy no one's the purpose of, then.
