Whatever they do, I hope they try to match the format of the 1/3 JH when designing this guy's base. I want to see that black hexagon/diamond border around it and I'd like it to be the same size. That way it's clear they're from the same line and they'll be guaranteed to fit on the same type of table/pedestal/etc.
An alleyway or slaughterhouse theme would be cool because they can bring back the translucent water effect, but I'm not sure what elements they can fit on there to make it interesting. Maybe a fallen cut of beef or the barrel with King Willy's "psychic" bones scattered on it.
Pose-wise I'm a big fan of the spear, but I'd prefer him to hold it vertically at his side so it doesn't stick out of the piece too much.
