The Mythos Vader is an amazing piece, overall, and the orange actually doesn't look too bad in person. I would have preferred less orange but you have to remember that the effect is there as an integral part of the story that the piece is telling. I'd also have preferred a pristine Vader suit but that wouldn't have fit in with the story either, in my opinion.
I don't know how the PF is going to outdo the Mythos but I am really looking forward to it because I'd like a 1/4 scale Vader in a pristine suit with a powerful pose.
