Hmm, I don't know if yours are fake or not, but poor handiwork isn't an exception even when it comes to original ayupans.
For example, I bought a few ayupans during AT10. The Encore one can't really stand, the NL one has a slightly crooked nose, and the In the Corner one had some bad colouring on her hat. So yeah, being original doesn't mean it's high-quality. Though this year's ayupans do have especially poor handiwork somehow, I was quite shocked when I was examining them.
