Sorry to nitpick here too Matt, but I really like almost everything about this cool design of yours too, except the skull.
I was thinking in place of the skull have you perhaps thought about either a figure of the "Lion Rampant"(the famed U.K. lion reared up on his hind legs with it's paws out forward), or maybe the head of an english bulldog in about the same size and scale as that skull? I think that would be pretty cool and would continue the theme that you've got going on here.
Yep! Just like a good Single Malt Scotch, you might call me "an acquired taste" TOO.(among the many OTHER things you may care to call me, of course)
