Holy s###. That's really good!
My only suggestion would be to do something else with the centurion (argonaut) figure. He's kinda out of place, stuck in the middle there.
You know what would be REALLY cool? Putting the centurion logo on a bottle neck label. That would be killer. And then you'd have somewhere to describe the beer.
And maybe change the centurion's eyes. He looks bored.
As with all of my suggestions, feel free to tell me how wrong I am.
