1. No sure who are these girls but, indeed, they wouldn't look very exotic, at least here in Poland. 2. You use people mixed with Tatars as an example of Slavic features?;-)
Having lived in a 50% Slavic city for most of my life, I can say that Slavic look usually = slutty, ugly and too much make up. People who like slutty women, will think that Slavs are attractive.
