Let's not forget how diverse Russia is. Oh well, Russians are indeed very diverse. There are a lot of them and a lot of them are very different. The only only other country which as diverse as Russia is US. Liza is your not typical "European Russian" and not a stereotypical blond-blue-eyes regular Slavic girl. She is a Tatar or Udmurt, iirc. So, yeah, there are probably some Asian/Middle Eastern culture in her. She was born somewhere close to St Petersburg, AFAIK, but that's her genes. That gives her flavor and different style. I'm all in for diversity in styles, cultures and choreography.
