Portrait wise the teeth is better on the 1/3 but that's about it. 1/2 scale still has a better head sculpt. Also the nose cavity is a little too big on the 1/3 and the slightly oversized teeth together has thrown off the proportions of the portrait.Sold!! The endoskull alone is a huge improvement over the 1/2 scale IMO.
What we are seeing is also the prototype, if you compare it to 1/2 scale prototype which had near perfect teeth, the 1/3 doesn't even come close.
This statue preview has obvious flaws, I'm surprised people are willing to overlook them.
