Spring Kairin is very lovely! I like the way that she's drawn. If she were a real girl, I'd have to steal a couple of looks... (But I wouldn't just stare...)
Anyway, the two things that did make me nervous were a) the small fingers and b) the shoulder. But those two things are really minor, and can be easily dismissed as "that's just how she is." Konzept's modifications are pretty nice, I think.
I completely disagree with Dan. In fact, Kiva128, please draw Kairin more often in jeans like that. I like my women in jeans.
