Unpainted chin -> one more less thing to worry about.
I decided to collect only female busts, but if they were to re-release every Marvel character with one arm I'd have a hard time resisting them. Characters such as Punisher and Wolverine are just begging for one.
But then...
* I think these pieces can only have so much variety regarding arm position.
* This is a movie Iron Man bust, not a comic-book one, so when it comes to Marvel it's probably just a one-off, unless they're offering other movie-related LSBs, which I'm not interested in.
* I don't see SSC revisiting any Marvel characters for this line when there are still so many interesting ones left to tackle, even though some would likely be big sellers.
Still, the last one to be pre-ordered before this Iron Man was Gambit, and that was quite a long time ago, so I'm really waiting for what comes next. If it's a comic-inspired LSB with one arm, I'll cave in and order this Mark VI. Otherwise, it's a really, really nice piece but I'll pass.
Oh, and the base is gonna make it or break it, too. I too dislike the Star Wars LSBs in that respect.
