It's all a matter of opinion, you know. There will always be people that won't like Barbara's work or her poses, no matter how hard she tries. You will always find a person out there which will tell you that they find her boring or an average looking replaceable face. Different people, different opinions. Not everyone will like her. And if someone finds her boring, one-dimensional or lacklustre, then so it'll be. You can't change people's opinions on someone. Besides, it doesn't mean anything anyway. If Barbara would be a bad or boring model no one would book her. But they do, so she must be doing something right.
It's not only about opinions, you know? It's also about experiences. I don't know what is exactly the age of the "average" Barbara's fans on BZ but according to my "old" experiences I can tell you Barbara is not a versatile model. Will she be one, one day? Sure, because she has everything to become a great model.
Nobody said she was a bad model by the way.
