Hmm... seems I missed all the fun.
So much
crap has been said that I don't even know where to start, so maybe I just won't even try to.
But I will say this:
The inaccuracies on the HT figure (which I own, along with a bunch of other HT figures) are not just around the mouth and dome. The entire sculpt of the figure is off, with a lot of invented details thrown in.
The inaccuracies on the NECA figure are clearly only around the neck (which to me is understandable given how the joint was sculpted into it) and dome area. The mouth itself is fine. The problem is that the lower jaw sits a bit too far back, a manufacturing error that prevents it from closing fully and makes the upper teeth jut forward. How do I know this? Because I saw the prototype:
Hope it's alright to post the pic Kyle.
What's the point you may ask. The point is, Tankman sculpted the figure to the absolute best of his ability, asking in various boards for reference pics of the alien to try and sculpt the best figure of the alien ever.
In contrast, if you look at Tsang's blog, you can clearly see McFarlane's figure as reference on Tsang's desk. How do I know he used it as reference? Because many of the mistakes and invented detail on Tsang's figure are the same that can be found on McFarlane's effort. What does that tell me? That he didn't really give a damn about accuracy. And the result shows it clearly enough.
Tankman has even been graceful enough to come in here (and on other boards) to discuss the shortcomings of his own work and praise other sculptor's work, like the Medicom figure.
He even acknowledges the "cool" factor and intricate work of less accurate figures like McFarlane's and HT's.
I too believe Tsang works under a very tight schedule and is not given the time to fully research the aliens in general, as Kyle pointed out. Also, I don't think it is unfair or insulting to wonder if Tsang is really at the peak of his talent, after all, it clearly is a lot more difficult to sculpt something accurately than to just do your own thing loosely based on something.
I myself questioned his prowess as a sculptor after seeing that both the A3 dragon and the Big Chap were his work. Both very inaccurate and not really very true to the vision and feel of the screen creatures.
And last, but not least, if someone comes and opines that a figure that is clearly inferior in sculpting accuracy is more accurate than the one you have made (which is clearly more accurate from every single point of view), I think you have all the right in the world to point out how mistaken that person is. Especially if said person comes in with attitude to insult you and the company you work for.
Now I'm going to go back and enjoy looking at the wonderful pics Sabres shared with us and play with my NECA, Medicom and HT aliens. And the McF too, what the hell!
