Yeah, I've looked into it before. It's not unfinished - the problem is the bones were set to render. But it's not as simple a fix as the Duros thing, unfortunately. The three main issues are that the camera is moving, the commoners have shadows, and there's dust flying around. That makes removing them from the shot a lot harder. The two options are to rotoscope the bones to change their color, which wouldn't be fun and would never look perfect, but would at least make them stand out less... or redo the whole shot. I might look into it again at some point, but I have no specific plans at the moment.
It's also not especially obvious, but one of the commoners is Queen Talia.
