Don't buy that. The Chinese would make whatever's thrown at them in the blueprint. SS are the ones who've done a piss poor job at the design stage.
It all comes down to SSC's sculptors doing a poor job of basic observation - looking at the reference pics or in-hand props and reproducing the shapes, details and proportions correctly. It is first year art school stuff.
I have noted time and again as I have looked over SSC figs how it would have cost no more - and been no more effort - to have gotten a certain detail or proportion right than gotten it wrong. And honestly, it's more often than not that it is wrong - usually, slightly off, but not uncommonly quite a ways off.
It has nothing to do with compromise due to materials or manufacturing, or limitations of scale. Maybe they don't have enough time to get it right - but then some of these figs are in development for years, so that's hard to believe.
I think it clearly comes down to them feeling like being 3/4's accurate is enough. And they would probably say "it's good enough for most average collectors and it's a tiny percentage that nitpick and they'll buy it anyway" but at this level and price I'm not sure that's a good mindset going forward.
While HOt Toys does get things wrong too (their Indy has many inaccuracies) in general, they are in a class above SSC. I'm not talking about quality of facial sculpt and paint apps - I'm talking about that basic, general eye for accurate reproduction of shapes, details and proportions.
I think SSC continuing to ignore this - and we talking about version 2 of the most iconic character in the Star Wars universe here - will begin to erode their business and leave them behind as this hobby evolves to be higher and higher end and the pond shrinks, led by the likes of EB and HT.
Right now SSC's figures are a decent upgrade on their old $50 figs of 3-6 years ago, but without a doubt they are lagging. They have upped their focus on PF, contracted an alliance with HT to make some profit on HT's usurping some their key licenses, but them making their own 1/6 is where a lot of the big money is and I hope they raise their game and not wave the white flag to those who lead currently due to these basic issues of accuracy.
They have been greatly improving lately but their efforts so far with this second Vader have me concerned. It doesn't look right to me in an overall sense and I'm not even a huge Vader-phile re: the size of dome etc. Yep, it looks like Vader, but that would have been fine at $120 like the last one, not at the HT price point this will be. And the idea of "they'll buy it anyway" has been eroded by the tantalizing "maybe HT will do a Vader in a year or so" - SSC can't have its cake and eat it too.
