I respectfully disagree.
The old Miru looks like what the western stereotype of what Asians should look like.
The new Miru looks like an actual Asian.
I'm Asian, so I'd like to think that I should know.
But of course, this is all subjective.
I mean I'm Asian too, and I think it's the other way around.
At least old Miru looks like a Korean/Japanese idol.
New Miru looks too "western". Her new appearance have many traits regular Asians don't even possess.
Why does she have different colored eyes? Is that blue?
Why are her eyes too big?
Why does she even have freckles.
These are all traits not inherent or common for an Asian.
Yes there are some like this, but that's uncommon.
If we're going for an Asian look here, then the old model would be "Asian"er, without the traits a westerner would have.
You could argue the new looks exists on some Asians, maybe in the southeasterns, but Miru is a Japanese name, so if we are going by who looks more Japanese, then the old one is.
Yes it looks like your stereotypical Asian girl model who cosplays or loves anime and shit, but at least you know it's Asian in first look.
The new one you won't be able to tell unless you're told she's Asian. Especially with those freckles.
