Necas godzilla looks great because it's from the digital file (but then so are many of the other toys out there of legendary G, like the Japanese cup topper, a simplified jakks, etc....this explains the shortcomings of the other godzillas shown by neca....
That said, even though Sakai's G isn't accurate, he has done a decent job....for a sculpt that's not from the digital file, and it being "sculpterly" in his usual render, it's pretty good considering the other hand sculpted items we got from bandai America (excluding the hyper sized G from the destruction series and the new vinyls -u.s. And japan- coming out)
The artists who have typically captured Godzilla with great success,
I'm talking about two masters, Art Adams and Yuji Sakai have both had difficulty in capturing a really definitive likeness of Legendary G.
That's a good sign of its uniqueness and that time will still determine for us what makes that godzilla truly stand out......
It's like when vader first appeared....all anyone saw was the triangular mouth, black silhouette and samurai dome. And that was enough to depict him....still is for some. But now we've become so familiar, with him, the nitpicks are rather intense....down to details we know to exist but are perhaps never seen on screen.
For me, the stance for Legendary is really characteristic of his design.....the way the arms can hang down vs the typical bent elbow look of the Heisei and millennial G's....one reason the sh monsterarts looks weird....always in outlandish poses to showcase the articulation, but it doesn't help to establish his uniqueness as legendary G.....
The broken glass look of his dorsal spikes which are symmetrical all the way down his back on both sides, the short, square muzzle, small eyes, square head, webbed fingers, turtle legs and feet, armored hide vs the tree bark "burnt" texture of the skin we've become so familiar with....tapeworm-like segmented tail, vs the long flexible fat tail we've gotten used to.....these are things that seem to define his look
