The helmet needs to have more flair to it and the eyes are too red. They should be more of a brown-amber. Hopefully they will fix it before production begins.
By the way, I know this Vader is labelled "A New Hope" but he looks very much like the Vader we see in Rogue One, particularly in the mask and dome (shape and shiny finish).
Just got this Vader after a long hesitation and man, am I glad I finally did. From the stance, to the red lenses, to the intricate crisp details, to the flawless paint app, it was well worth the money. I love it!
Here's a couple of not-so-good pics (it is quite dark right now). I'll post more this week-end.
