To be honest, I really love the concepts behind these PVs... GREEN was visually stunning, nevertheless Ayu's face in the beginning is honestly a turn off, and the weird transitions are honestly confusing and illogical.
Sparkle was the best out of all Kazu's PVs, but still, the concept was fantastic with the 4:3-16:9 ration change, but when she did all her "sexy" movements... they feel really forced, unnatural and uncomfortable.
I've mentioned in the ECSTASY vs Sparkle PV poll that Ayu can look naturally sexy if she wants to; just look at (don't) Leave me alone and my name's WOMEN @ AT 08.
But in Sparkle, I felt as though Kazu made her do things she's just not comfortable with...
Mirrorcle World; I've not watched this enough to say anything, but it looks pretty and visually stunning like GREEN but when she started prancing around in the streets of Paris with her omg-face... it's just
That being said, I don't really like some of her old videos too, because I find them plain/uninteresting. But they have better transition and technical stuff than the 3 Kazu PVs.
