I swear Ryo and Shenhua's models just keep getting better and better with each new appearance; they really appear to be coming into their own with this particular revision. Even though we're only able to see Shenhua from a side-on perspective, her face has been massively improved compared to her derpy Gamescom look.
Just look at the difference from August 2017 compared to now:

Those gorgeous environments, too =P~ =P~ =P~
I don't see the difference in the actual model tbh.
His eyes are squinting a bit due to him actually having facial expressions.
But the model itself? Looks the same. I agree with whomever said his proportions are a little off, and his facial features are a little feminine.
Seems Yu's main aim is to make Ryo "handsome" and Shenhua "cute", as opposed to making them closely resemble their original models.
