[SPLIT LIP]

I dunno, obviously the show helmet has sharper details, but it looks pretty accurate to me. (going off of Google images) Aside from the antennae obviously not being as thin, the line of ridges that comprise the "mouth" seems just a tab more rounded on the Renewal than the slightly more square arrangement on the show helmet. But that's the very definition of slightly. Otherwise the shapes all look spot-on.

As for proportions, I can certainly see your issue. The Renewal, while noticeably bulkier than the original, is still much slimmer than the TV show costume. That said, SS figures are also slimmer but not to Black's degree. (Black seems about in between an old Figuart and SS as far as relative/accurate bulk is concerned) But again, this seems like a very minor quibble.

Then again, it's also a gift so maybe I'm less critical. (then again I've always been highly critical of Figuarts) But it looks like maybe a half-step behind SS. Even if I was paying he's around the $30 mark if you look, which I guess makes him an easier pill to swallow in terms of inaccuracies compared to an often $50-60 SS Figuart.
