>>105190 (OP)
Ok I'm gonna go overboard on this. Very important specific point to notice is the eyes, which is what struck me as the most immediately off about it - and it's not just the rig, I think it's the model art.
Looking over the chibi model in
>>105363 we see that
-The eyes are well distinguished from the rest of the face.
-In a relaxed expression the lower lids of the eyes have a natural slight downward curve.
In the new model's face as seen in
>>105190 (OP),
>>106909,
-In *every* expression, the lower lids of the eyes have a constant *upward* curve, as if in a permanent smile or permanent mid-blink. This is unnatural, and it eats into the space occupied by the lower part of her iris, so she's losing like 1/4 to 1/3 of her eye expressiveness there. It makes her eyes smaller than they should be. This upward curve is fine for a transitory expression like blinking, or when tracking actually detects that her IRL lower lids are reacting to a strong smile, but it is wrong when it's constant. And it is like this even in her crying/angry/etc expressions.
-The whites of the eyes on the inward side also blend into the color of the face too much IMO, and again contribute to making her eyes look unnaturally small.
-With these factors, adding in that her hair in the new model is encroaching in on those eyes too... it's just wrong enough.
Conceivably what I'm talking about with the lower lids is a fixable rigging problem, but I don't think so. I think the art itself is like that.
I also noticed that these eyes are a bit of a departure from Asagi's artstyle. If you look closely you can see that these eyes have the same ring structure that Fauna's and others' have and get the family resemblance, but I can't see any instance where Asagi has done this lower lid thing before, and also the iris coloration also seems more textured. This itself isn't really a point against it. But what if there was a combination of "going all-out for a new model for an important person" and "trying new things" happening here, and it just didn't quite go right.
