Certainly an issue to be concerned about. You can also see the brass post that holds the crown in place. That had better be fixed 'cause if I get one looking like that I'll be sending it back.
My greatest issue with the bust isn't the sculpt itself [which seems to be the biggest complaint of most people], it's the pathetically lame base. What does placing him on a base with elvish writing on it have to do with the witch-king? Where's the nameplate and the theme-related base [in this case weathertop] we have gotten with every other "bad guy" LSB
SS can put whatever spin they want to on this, but this has all the feeling of something they have rushed into production, and IMO it's where they really dropped the ball with this bust
